▼ The catastrophic consequences associated with landslides necessitate predictions of these hazards to be made with as much certainty as possible. However, the often complex nature of these events make predictions highly challenging. In this thesis, a number of hypotheses related to the triggering mechanisms and subsequent consequences of landslides in a loose-granular soil were investigated. The investigation was conducted using small-scale geotechnical centrifuge models, and a new flume facility developed to examine landslide behavior in a reduced-scale model. The first hypothesis explored in this research was that static liquefaction might preferentially occur in the saturated granular soil located at the base of the landslide rather than the well-drained inclined portion of the slope. Using a geotechnical centrifuge model, it was found that a small initial toe failure did act as a monotonic loading trigger to shear the loose contractile saturated sand at the base of the slope and caused liquefaction to occur. The second hypothesis investigated whether the consequences of a landslide triggered under elevated groundwater antecedent conditions are higher than scenarios under drier antecedent conditions. Results from five centrifuge models subjected to different antecedent groundwater conditions show that higher groundwater conditions can result in landslides with velocities about three times higher and travel distances eight times higher than low antecedent conditions. The third hypothesis investigated the influence of slope inclination on landslide consequences. Seven geotechnical centrifuge models were built and tested, comparing the consequences of landslides triggered in 20° and 30° sloped models with different groundwater conditions. The results of these tests found that the influence of slope angle on the mobility consequences of a triggered landslide are highly dependent on the antecedent groundwater conditions. The most significant case was under high groundwater conditions, where the shallower 20° slope travelled twice the distance and speed of the steeper 30° slope. A new flume facility was developed to examine landslide behaviour in a reduced-scale model, and a direct comparison was made to one of the centrifuge models from the research. The comparison demonstrated the challenges associated with using reduced-scale models to study suction-dominated problems such as hydraulically-induced landslides in loose granular soils.

▼ Flood evacuation models can provide an effective mechanism to analyse flood risks andevacuation response actions. In this study, practical applications of evacuationsimulation models are presented to help examine flood-related evacuation scenarios.Simulation frameworks are demonstrated through the case studies of Brisbane City,Queensland, Australia, which has a long history of floods and has experienced majorflooding events in 2011 and 2013. These case studies were investigated to demonstratefeasible applications of flood extent prediction, network bottleneck estimation, evacuees’behaviour and shelter demand, which contribute to flood risk mitigation and evacuationplanning. The proposed flood evacuation models are proven to help increase communityresilience in at-risk areas in Brisbane.Effective flood emergency management needs an integrated operation of interactingwith human and technological systems. In this study, firstly, spatial toolkits areemployed to analyse the shelter assignment and routing strategies based on networkcalculations. Simulation results indicate that the nearest shelters and routing directionscan be determined based on the unique location of each household. To analyse thetemporal flood risks and identify dangerous areas, an inundation model is proposed toprovide flooding information for a dynamic risk analysis study. Test results of theinundation model show that it is able to predict the flood inundation extent at anaccuracy of 66.9% which is higher than or comparable with the existing studies.A large-scale inundation can affect the endangered areas progressively and the temporalaspect of the incident should be captured in evacuation planning. By integrating thesimulated flood dynamics, a city-scale microscopic evacuation model is built through anagent-based approach; different flood stages associated with departure times and variousbehaviour rules are tested for the Brisbane evacuation scenarios. The inclusion of flooddynamics in the evacuation model is essential for identifying temporally critical locations in the network as it provides a perspective to observe the dynamic interactionsbetween evacuees and floodwater. In the agent-based flood evacuation scenarios, morethan 12,000 evacuees are simulated and less than 7% of evacuees were still movingtowards shelters after 120 minutes since the evacuation started. Evacuees are moreevenly distributed in the pre-determined six shelters when more complex behavioursuch as evacuee density detection is considered. A static traffic assignment approach isalso implemented towards simulating the urban evacuation scenarios. The results of thetraffic assignment approach show a much less network clearance time compared to theagent-based approach, which reveals the difference between these two models in termsof input, modelling algorithms and output. Suggestions are provided for the choice ofmodelling tools based on this comparison analysis.Overall, the flood evacuation model enables explicit interactions among evacuees andbetween human response and floods to… Advisors/Committee Members: Lim, Samsung, Civil & Environmental Engineering, Faculty of Engineering, UNSW, Rey, David, Civil & Environmental Engineering, Faculty of Engineering, UNSW, Sharples, Jason John, Australian Defence Force Academy, UNSW.

▼ This is a PhD thesis by publication consisting of four journal papers and two chapters in books. Each manuscript details the geological characterisation that has underpinned scientific field research and operations at the CO2CRC Otway Project. This is Australia’s first site to geologically store carbon dioxide and has been operating in Victoria, Australia, since 2008. Site screening, planning, and development began four years prior to that. During the course of the past 14 years the project has achieved demonstrated storage in both a depleted gas field, and a saline aquifer, and investigated the dynamic processes and monitorability of both scenarios in a series of controlled field experiments. This has provided a unique opportunity to test and validate interpretations of the geological characteristics that are thought to influence storage efficacy and containment. The research presented in this thesis has the distinction of being able to test geological heterogeneity at both the core and field scale by comparing the core analysis and laboratory experiments with actual injection data. It shows that small scale geological influences, particularly vertical permeability, have an impact on capacity and trapping. Furthermore, the time-lapse monitoring datasets provide evidence to which the conformance of reservoir models are assessed. The body of work herein has established that valuable insights may be used to improve site characterisation before, during, and post-injection. This is particularly important for updating models to enhance reservoir management, as well as for predicting the longterm evolution and stabilization of injected CO2. This in turn will influence enduring monitoring strategies and the potential transfer of liability for many sites post-closure. The research presented here examines the whole of life site assessment process from site selection through to execution and completion. It dispels the myths that depleted fields have little uncertainty and risk because they have held hydrocarbons in the past and are already well characterised by the previous operators. Instead the findings show that characterisation for CO2 storage has very a different focus from that of petroleum exploration and development methods, and targeted data acquisition and integrated analysis is essential to reduce uncertainty. The study also shows that information gathered for CO2 storage site characterisation of a previously poorly characterised saline aquifer can have greater implications for the regional understanding of basin stratigraphy and geological controls on fluid migration. Thus the investigations may be of interest to those beyond just the carbon capture and storage research community.

▼ Stationary (static) shoulder friction stir welding (SSFSW) is a variant of conventional friction stir welding (FSW) that was originally invented to improve the quality of welds produced with titanium alloys. Its predominant advantage is a reduction of the severe through thickness temperature gradients seen in conventional FSW, when welding low thermal conductivity alloy. However, SSFSW has rarely been utilised as a method to weld aluminium alloys because it is generally thought that in conventional FSW the rotating shoulder plays an essential role in the heat generation and, due to the high thermal conductivity of aluminium alloys, a rotating shoulder is beneficial for the welding process.In the work presented, the advantages of SSFSW have been examined when welding a typical high strength aluminium alloy AA7050-T7651. The process window for each approach has first been determined, and the optimum welding conditions were systematically evaluated, using power-rotation rate curves. Direct comparison of the two processes was subsequently carried out under these optimum conditions. It has been demonstrated that SSFSW can dramatically improve the quality of a weld’s surface finish. Under optimum conditions it has also been shown that SSFSW was able to weld with approximately a 30% lower heat input than FSW and the stationary shoulder led to a narrower heat affected zone (HAZ). As a result, the through thickness properties of SSFSW were much better and more homogeneous than that for FSW, in terms of grain sizes, hardness and cross-weld mechanical properties. Uniaxial tensile tests proved that the average tensile strength of SSFSW samples was around 500 MPa, which was about 100 MPa larger than that of the FSW sample. Also, it was shown that during tensile testing the deformation zones, which correspond to minima in the hardness distribution of SSFSW welds, were about half the size of those found in FSW welds under the same traverse speed.The mechanisms that give rise to these advantages have been investigated systematically, focusing on directly comparing the SSFSW and FSW processes, and are discussed aided by finite element modelling (FEM) of the heat distribution in welds produced by each process and microstructural investigations.

The art of structural design requires specific methods and tools. One of those consists in modelling the structural behaviour through a network of straight bars, whether in compression (struts) or in tension (ties), and in expressing its static equilibrium through classic graphic statics reciprocal diagrams: a form diagram describing the geometry of a strut-and-tie network and a force diagram representing the vector equilibrium of its nodes. When it comes to statically indeterminate structures, the lower-bound theorem of Plasticity avoids any overestimation of the load bearing capacity, which allows the designer to select one of the possible equilibrium states. Considering that a limit state analysis of these indeterminate equilibriums can better support the design process when it shares the same graphical environment, the thesis consists in proposing a graphical methodology for constructing a parametric force diagram resulting from the combination of independent force diagrams. The stress distribution is then modified by manipulating the relative position of some vertices of the force diagram until it reaches limit states; hence, the possibility of identifying the collapse state and the corresponding load bearing capacity of various types of structures such as pin-jointed trusses, beams or masonry arches. The analysis of the admissible geometrical domains for these specific vertices allows a better understanding of the behaviour of statically indeterminate structures at limit state and may be helpful when designing them.

La conception des structures est un art aux visées multiples – intellectuelle, fonctionnelle, esthétique, écologique – dont la pratique requiert l’usage de méthodes et outils spécifiques. Parmi ceux-ci, la conception plastique à l’aide de modèles de bielles-et-tirants tient une place particulière par l’extrême concision de ses fondements théoriques, la grande liberté qu’elle accorde au concepteur et la lisibilité des résultats qui en découlent. Prenant appui sur le théorème statique de la Théorie de la Plasticité, elle propose de modéliser le comportement des structures par un réseau d’éléments comprimés et tendus en équilibre avec les charges appliquées et dont la résistance est assurée par un dimensionnement approprié. Cet équilibre peut être vérifié et manipulé à l’aide des diagrammes réciproques de la statique graphique : le diagramme de situation (F) qui décrit la géométrie du réseau de bielles-et-tirants, et le diagramme des forces qui en représente vectoriellement l’équilibre statique (F*). Or, la modification des conditions d’équilibre de ce réseau en vue d’en améliorer les performances structurales résulte fréquemment en des diagrammes de situation statiquement indéterminés, et partant de diagrammes des forces géométriquement indéterminés, dont l’analyse doit permettre d’identifier les cas limites susceptibles de conduire la structure à la ruine. La thèse ambitionne dès lors d’identifier ces cas limites par l’analyse géométrique des relations qui lient les diagrammes réciproques. Au…

▼ The behaviours of braced steel frame members and components are investigated in this project using finite element models that were developed to address the multi-scale mechanics of braced steel frame structures. The multi-scale mechanics are based on three assessment scale levels; that is, material (coupons), elemental (bracing steel structural members) and component (brace gusset-plate structural members) levels. Each finite element model was validated with data from physical laboratory tests. The models were then used to assess the current European code of practice in the seismic design of braced steel frames, as well as existing empirical models and numerical models, and to derive new relationships for a number of design parameters. The framework developed for finite element modelling of steel concentrically braced frame structures followed conventional guidelines for 3D non-linear modelling but included novel advanced modelling techniques such as the extended finite element method-based crack growth model development, automated generation of initial imperfections in the brace member and an innovative material modelling methodology application. Importantly, realistic detailing for gusset plates and brace members were employed in the study. The framework of modelling was developed in the commercial finite element package ABAQUS v.6.13. The performance of finite element models was assessed against various measured parameters obtained from physical laboratory tests, such as buckling compressive loads, initial yield load, tensile load, ductility capacity, energy dissipative capacity, cycles to initiation of global and local buckling, fatigue-life capacity and failure modes. It was found that the finite element models predicted these response features within engineering accuracy, for multi-scale mechanical behaviour of braced steel frame members and components, when subjected to both static monotonic and cyclic ultra-low cycle fatigue loading regimes. Thus, the finite element models proposed in this study can be used with confidence both in academic studies and by engineering professionals for analyse and design of safer and robust structures, as they were calibrated and validated using physical test data.

Actuellement, la restauration des oeuvres d’art, notamment des statues fracturées, repose sur des techniqueséprouvées, mais empiriques. Les statues endommagées comportent souvent des parties brisées. Leur restaurationconsiste la plupart du temps à les rassembler. Ainsi apparait la nécessité de prendre en compte lespropriétés mécaniques des interfaces entre les différentes parties brisées, ce qui permet de limiter l’ampleur desréparations et ainsi, de mieux conserver l’intégrité de l’oeuvre. Par ailleurs, les techniques numériques d’acquisition3D font leur entrée au service de la conservation du patrimoine. Cette thèse propose une méthodologiecapable d’utiliser des données issues d’une acquisition 3D pour simuler les opérations de restauration et leurseffets sur la structure de l’oeuvre. Les processus de restauration peuvent ainsi être testés et optimisés.Un scanner laser est utilisé pour l’acquisition de la géométrie des oeuvres, ce qui nous permet de reconstruireun modèle 3D pour la simulation numérique. Les calculs sont menés dans le cadre de la mécanique des milieuxcontinus déformables avec FLAC3D. Pour vérifier tous les points clés garantissant la stabilité mécanique, lecomportement des éléments de renforts et celui des interfaces entre les blocs ont été considérés. À partirdes résultats de ces études, une critique des stratégies de restauration mises en oeuvre ou envisageables estproposée.De plus, plusieurs méthodes de caractérisation visant à retrouver la provenance du matériau et/ou estimerles propriétés mécaniques de l’oeuvre sont proposées : caractérisations physico-chimiques et minéralogiques,essais non destructifs et destructifs. Une campagne expérimentale visant à caractériser le comportement desfractures en contact frottant avec acquisition de l’état de surface a été réalisée. Une analyse des corrélationsentre les propriétés mécaniques et morphologique des interfaces est ensuite élaborée. Enfin nous proposonsdes modèles prédictifs construits par régressions linéaires multiples et multivariées. Cette étude permet desimuler le comportement d’une oeuvre fracturée.

Currently, the artworks restoration, including broken statues, are based on proven but empirical techniques. Damaged statues often have broken parts. Restoration mainly consists in joining these parts. Thus appears the necessity of taking into account the interfaces mechanical properties between the different broken parts, reducing thereby the extent of repairs and thus better maintain the integrity of the work. Beside this, digital 3D acquisition techniques become more and more popular among the cultural heritage community. This thesis proposes a methodology able to use 3D acquisition datas to simulate the restoration operations and their effects on the structure. The restoration strategy can thus be tested and optimized. A laser scanner is used to acquire the statue geometry, allowing to reconstruct a 3D model for numerical simulation. Computations are carried out within the framework of deformable continuum mechanics using the FLAC3D…

▼ There is an increasing need for accurate models describing the electrical behaviour of individual biological cells exposed to electromagnetic fields. In this area of solving linear problem, the most frequently used technique for computing the EM field is the Finite-Difference Time-Domain (FDTD) method. When modelling objects that are small compared with the wavelength, for example biological cells at radio frequencies, the standard Finite-Difference Time-Domain (FDTD) method requires extremely small time-step sizes, which may lead to excessive computation times. The problem can be overcome by implementing a quasi-static approximate version of FDTD, based on transferring the working frequency to a higher frequency and scaling back to the frequency of interest after the field has been computed. An approach to modeling and analysis of biological cells, incorporating the Hodgkin and Huxley membrane model, is presented here. Since the external medium of the biological cell is lossy material, a modified Berenger absorbing boundary condition is used to truncate the computation grid. Linear assemblages of cells are investigated and then Floquet periodic boundary conditions are imposed to imitate the effect of periodic replication of the assemblages. Thus, the analysis of a large structure of cells is made more computationally efficient than the modeling of the entire structure. The total fields of the simulated structures are shown to give reasonable and stable results at 900MHz, 1800MHz and 2450MHz. This method will facilitate deeper investigation of the phenomena in the interaction between EM fields and biological systems. Moreover, the nonlinear response of biological cell exposed to a 0.9GHz signal was discussed on observing the second harmonic at 1.8GHz. In this, an electrical circuit model has been proposed to calibrate the performance of nonlinear RF energy conversion inside a high quality factor resonant cavity with known nonlinear device. Meanwhile, the first and second harmonic responses of the cavity due to the loading of the cavity with the lossy material will also be demonstrated. The results from proposed mathematical model, give good indication of the input power required to detect the weakly effects of the second harmonic signal prior to perform the measurement. Hence, this proposed mathematical model will assist to determine how sensitivity of the second harmonic signal can be detected by placing the required specific input power.

Afin de permettre le développement de modèles manipulables par les concepteurs, il est nécessaire de pouvoir comprendre le fonctionnement des nanotubes, en particulier le transport des électrons et leurs propriétés électroniques. C’est dans ce contexte général que cette thèse s’intègre. Le travail a été mené sur quatre plans : développement de modèles permettant la description des phénomènes physiques importants au niveau des dispositifs, expertise sur le fonctionnement des nano-composants permettant de dégager les ordres de grandeurs pertinents pour les dispositifs, les contraintes, la pertinence de quelques procédés de fabrication (reproductibilité, taux de défauts, collection de caractéristiques mesurées et développement éventuel d'expériences spécifiques, expertise et conception des circuits innovatifs pour l’électronique numérique avec ces nano-composants.

This PhD work presents a computationally efficient physics-based compact model for the Schottky barrier (SB) carbon nanotube field-effect transistor (CNTFET). This compact model includes a new analytical formulation of the channel charge, taking into account the influence of the source and drain SBs. Compact model simulation results (I–V characteristic and channel density of charge) as well as Monte Carlo simulation results, which are provided by a recent work, will be given and compared to each other and also to experimental data to validate the used approximations. Good agreement is observed over a large range of gate and drain biases. Furthermore, a scaling study is presented to examine the impact of technological parameters on the device figure of merit. Then, for the assessment of the SB on circuit performances, traditional logical circuits are designed using the SB-CNTFET compact model, and results are compared with a conventional CNTFET with zero-SB height. Finally, exploiting the particular properties of SB-CNTFETs, a three-valued static memory that is suitable for high density integration is presented.

▼ In the modern built environment, building construction and demolition consume a large amount of energy and emits greenhouse gasses due to widely used conventional construction materials such as reinforced and composite concrete. These materials consume high amount of natural resources and possess high embodied energy. More energy is required to recycle or reuse such materials at the cessation of use. Therefore, it is very important to use recyclable or reusable new materials in building construction in order to conserve natural resources and reduce the energy and emissions associated with conventional materials. Advancements in materials technology have resulted in the introduction of new composite and hybrid materials in infrastructure construction as alternatives to the conventional materials. This research project has developed a lightweight and prefabricatable Hybrid Composite Floor Plate System (HCFPS) as an alternative to conventional floor system, with desirable properties, easy to construct, economical, demountable, recyclable and reusable. Component materials of HCFPS include a central Polyurethane (PU) core, outer layers of Glass-fiber Reinforced Cement (GRC) and steel laminates at tensile regions. This research work explored the structural adequacy and performance characteristics of hybridised GRC, PU and steel laminate for the development of HCFPS. Performance characteristics of HCFPS were investigated using Finite Element (FE) method simulations supported by experimental testing. Parametric studies were conducted to develop the HCFPS to satisfy static performance using sectional configurations, spans, loading and material properties as the parameters. Dynamic response of HCFPS floors was investigated by conducting parametric studies using material properties, walking frequency and damping as the parameters. Research findings show that HCFPS can be used in office and residential buildings to provide acceptable static and dynamic performance. Design guidelines were developed for this new floor system. HCFPS is easy to construct and economical compared to conventional floor systems as it is lightweight and prefabricatable floor system. This floor system can also be demounted and reused or recycled at the cessation of use due to its component materials.

Les Robots Parallèles à Câbles (RPCs) sont des robots parallèles dont les jambes se composent de câbles. Les applications industrielles potentielles des RPCs sont nombreuses telles que le grenaillage et la peinture de structures massives et de grandes dimensions.La première partie de ce manuscrit est dédié à la modélisation des RPCs. Deux modèles élasto-statiques ont été introduits dans ce manuscrit, pour décrire le petit déplacement de la plate-forme mobile en raison de la nature non-rigide des câbles. Le modèle élasto-statique basé sur des câbles pesants a été exprimé en faisant la différence entre la matrice de raideur active et la matrice de raideur passive du RPC.La deuxième partie de ce manuscrit traite de l’analyse d’espaces de travail de RPCs vis-à-vis de leurs performances statiques et dynamiques. Deux nouveaux espaces de travail ont été définis : (i) l'Espace des Vitesses Générables (EVG);(ii) l’Espace de Travail Dynamique Amélioré (ETDA). La troisième partie de ce manuscrit décrit une stratégie de conception générique de RPCs et des Robots Parallèles à Câbles Reconfigurables (RPCRs). Les reconfigurations sont limitées uniquement aux points de sortie des câbles. Dans ce manuscrit, les points de sortie des câbles peuvent être placés dans une large mais limité ensemble de positions. La stratégie proposée envisage la possibilité de déplacer les points de sortie des câbles du RPCR sur une grille prédéfinie d'emplacements.La quatrième partie de ce manuscrit présente un algorithme pour calculer une stratégie de reconfiguration optimale pour les RPCRs. Cette stratégie peut être utilisée lorsque l'environnement de travail de RPCRs est extrêmement encombré et qu’il n'est pas possible de prévoir le nombre de configurations nécessaires pour compléter la tâche.L'efficacité de l'algorithme a été analysée en étudiant les reconfigurations d’un robot parallèle à câbles planaire et d’un robot parallèle à câbles spatial en lien avec des applications industrielles.

Cable-Driven Parallel Robots (CDPRs) are parallel robots whose legs consist of cables. CDPRs may be used successfully in several industrial applications such as sandblasting and painting of large and heavy structures.The first part of this manuscript is dedicated to the modelling of CDPRs. Two elasto-static models have been introduced in this manuscript, in order to describe the small displacement of the moving platform due to the non-rigid nature of the cables. These models can be used for the modal analysis of the CDPRs, as well. The elasto-static model based on linear cables has been computed including the effect of the pulleys orienting the cables into the CDPR workspace.The second part of this manuscript deals with the investigation of the workspace of CDPRs, in terms of their moving platform static and dynamic equilibria, and in terms of their moving platform kinematic constraints. Two novel workspaces have been defined: (i) the Twist Feasible Workspace (TFW); (ii) the Improved Dynamic Feasible Workspace (IDFW). The third part of this manuscript describes…

Este trabalho tem por objetivo principal a avaliação do desempenho de dispositivos de controle e da modelagem da carga a partir de Regiões de Segurança Estática. Trata-se de uma importante ferramenta para avaliação da segurança de sistemas elétricos de potência, utilizadas tanto em ambiente off-line de planejamento da expansão e operação, quanto em tempo real nos centros de controle e operação (sistemas on-line VSA). Estas regiões são obtidas através de sucessivas soluções de casos de fluxo de potência e seu objetivo principal é verificar as condições de atendimento a carga (mercado) a partir de diversas condições de despacho da geração. Inicialmente, portanto, é apresentado de forma detalhada o processo de construção das Regiões de Segurança Estática, bem como os principais aspectos construtivos e considerações relevantes que podem influenciar de forma significativa a análise do desempenho do sistema. Com este objetivo, foi desenvolvido um programa para construção automática das Regiões de Segurança Estática na plataforma MatLab. Um ambiente de processamento paralelo, intrínseco ao próprio MatLab, foi utilizado com o intuito de aprimorar o desempenho computacional, o que permite a avaliação tanto de sistemas de pequeno porte, de valor tutorial, quanto de sistemas de médio/grande porte. Numa segunda etapa, este trabalho objetiva avaliar o desempenho de importantes dispositivos de controle e modelagem de carga a partir da construção automática das Regiões de Segurança. Os dispositivos de controle avaliados são: (i) Controle Remoto de Tensão; (ii) Controle de Tensão por Bancos Shunt Chaveados Automaticamente; (iii) Controle Automático de Tensão por Transformadores tipo LTC (Load Tap Changer); (iv) Controle Secundário de Tensão. A influência da modelagem da carga na avaliação da segurança do sistema é investigada a partir dos modelos ZIP e motor de indução. Os resultados obtidos demonstram que a representação de dispositivos de controle e da modelagem da carga podem influenciar significativamente as Regiões de Segurança Estática de sistemas elétricos de potência.

The main objective of this work is to evaluate the performance of control devices and load modelling through Static Security Regions. This is an important tool for security assessment of electric power systems, which can be used for both the operating environment (on-line systems VSA) and planning studies.

Initially, the construction process of the Static Security Regions, as well as the key aspects of the construction and relevant considerations that may significantly impact the analysis of the system performance, is presented in detail. In this sense, a program for automatic construction of the Static Security Regions have been developed using the MatLab platform.

▼ It is generally accepted that underground geological storage of CO2 (GSC) in deep aquifers, is the option with the highest potential storage capacity. Detailed subsurface models with a high level of subsurface understanding are required for both estimation of CO2 storage capacity and GSC site characterisation. To attain this high level of subsurface understanding, models need extensive well data and good 3D seismic coverage, often not available at potential GSC sites. The technology of Stratigraphic Forward Modelling (SFM) has advanced to the stage where numerical simulation of the depositional processes can be used to predict reservoir properties at appropriate scales, away from wells and below seismic resolution. With these predictive qualities, SFM could potentially provide the subsurface understanding required in GSC, even in locations with limited well data and no seismics. This study assesses and demonstrates the potential role of SFM in rapidly generating a well-constrained static reservoir model for generic use in the GSC workflow. The eastern Australian Surat Basin is considered a highly prospective basin for GSC with several potential GSC sites. CSIRO' s Sedsim SFM package has been used to create a stratigraphic forward model of the Surat Basin, including a high resolution nested model of the EPQ-7 CO2 sequestration tenement located in the basin. The model simulates deposition and burial of the Early Jurassic Precipice Sandstone, Early to Middle Jurassic Evergreen Formation and Middle Jurassic Hutton Sandstone. A SFM workflow is devised, in which model results are translated to (pseudo)gamma ray values, to be directly compared to gamma ray well logs. This workflow enables an efficient model-to-well tuning process. The model is based on literature describing the depositional processes in the basin, followed by a process of tuning the model to limited well data. In the basin centre and EPQ-7 tenement, the model results display a good match with well data. The model-generated porosity and permeability values are reasonable, yet could use further refinement. Several potential applications in further GSC workflows are proposed for the model. Finally, it is concluded that this study demonstrates the high potential value of SFM, using Sedsim, in rapidly generating static reservoir models for use in GSC workflows, especially in areas with limited well data.

▼ The objective of this research is to model and analyze large strain problems (rolling, hot compression) in FCC polycrystals. In the first part of this research, a rate-dependent crystal plasticity based Element Free Galerkin (CPEFG) model was incorporated in commercial software LS-DYNA to simulate cold rolling of AA 5754. Unlike classical Finite Element Methods, EFG methods are meshless and hence can accommodate large strains. It is well known that rolling produces inhomogeneous microstructure in the through thickness of the sheet. Therefore CPEFG model used in this work accounted for the complete through thickness microstructure in the sheet. Through thickness deformed microstructure and strain distribution obtained from CPEFG simulations were validated with published results. CPEFG simulations provide elemental texture data which can provide insight into the microstructural changes during processing. Therefore, an in-house 3D framework (gCode) was developed. In-house gCode is based on a path finding algorithm and calculates the element neighbors to analyze subgrain formation and other grain metrics. Initial and final grain size in CPEFG rolling simulations was found using the gCode and validated against published experimental data. Results show a marked reduction in subgrain formation down the sheet thickness due to the reduction in shear. Further analysis showed that there was a 8 μm change in grain size between the initial and deformed sheet. However, there was a 7 μm change in grain size between the top and center of the deformed sheet. Thus highlighting the importance of capturing the complete microstructure of the sheet. In-house gCode was also used to study the relationship of grain size and texture across the sheet thickness. It is observed that small grains near the center of the sheet prefer Brass, S and Copper while large grains near the center of the sheet prefer Cube, S and Copper. Plane strain compression is often used to model cold rolling. Therefore, plane strain compression simulations were also performed and predictions from both simulations were compared. Volume fraction evolution of several texture components from the center section of the sheet show similar values between the two processes However, normal strains, shear strains and microstructure evolution near the top section show considerable difference between the two processes. Hence, highlighting the importance of using proper microstructure and boundary conditions for rolling simulations. The second part of this work focuses on through process modelling of hot compression of cast AA 6063. A Taylor based rate-dependent polycrystal crystal plasticity framework was used to predict the texture and stress-strain evolution at various temperatures (from 4000C to 6000C) and strain-rates (from 0.01 𝑠𝑠−1 to 10 𝑠𝑠−1). Crystal plasticity framework was modified to incorporate the effects of temperature and strain-rate. Proposed framework was calibrated, verified and validated with experimental AA 6063 hot compression Gleeble data. Simulated…

▼ Stationary (static) shoulder friction stir welding (SSFSW) is a variant of conventional friction stir welding (FSW) that was originally invented to improve the quality of welds produced with titanium alloys. Its predominant advantage is a reduction of the severe through thickness temperature gradients seen in conventional FSW, when welding low thermal conductivity alloy. However, SSFSW has rarely been utilised as a method to weld aluminium alloys because it is generally thought that in conventional FSW the rotating shoulder plays an essential role in the heat generation and, due to the high thermal conductivity of aluminium alloys, a rotating shoulder is beneficial for the welding process. In the work presented, the advantages of SSFSW have been examined when welding a typical high strength aluminium alloy AA7050-T7651. The process window for each approach has first been determined, and the optimum welding conditions were systematically evaluated, using power-rotation rate curves. Direct comparison of the two processes was subsequently carried out under these optimum conditions. It has been demonstrated that SSFSW can dramatically improve the quality of a weld's surface finish. Under optimum conditions it has also been shown that SSFSW was able to weld with approximately a 30% lower heat input than FSW and the stationary shoulder led to a narrower heat affected zone (HAZ). As a result, the through thickness properties of SSFSW were much better and more homogeneous than that for FSW, in terms of grain sizes, hardness and cross-weld mechanical properties. Uniaxial tensile tests proved that the average tensile strength of SSFSW samples was around 500 MPa, which was about 100 MPa larger than that of the FSW sample. Also, it was shown that during tensile testing the deformation zones, which correspond to minima in the hardness distribution of SSFSW welds, were about half the size of those found in FSW welds under the same traverse speed. The mechanisms that give rise to these advantages have been investigated systematically, focusing on directly comparing the SSFSW and FSW processes, and are discussed aided by finite element modelling (FEM) of the heat distribution in welds produced by each process and microstructural investigations.

▼ The Insurance Bureau of Canada released a report in 2013 that evaluated the seismic risk of two major metropolitan areas of Canada, with projected losses of 75bn in British Columbia along the Cascadia subduction zone, and 63bn in the east through the Ottawa-Montreal-Quebec corridor. Such reports should prompt researchers and designers alike to rethink the way that seismic design is approached in Canada to develop resilient and sustainable cities for the future. To mitigate the economic losses associated with earthquake damage to buildings in seismically active areas, controlled rocking steel braced frames have been developed as a seismically resilient low-damage lateral-force resisting system. Controlled rocking steel braced frames (CRSBFs) mitigate structural damage during earthquakes through a controlled rocking mechanism, where energy dissipation can be provided at the base of the frame, and pre-stressed tendons pull the frame back to its centred position after rocking. The result is a building for which the residual drifts of the system after an earthquake are essentially zero, and the energy dissipation does not result from structural damage. Design methods for the base rocking joint and the capacity-protected frame members in CRSBFs have been proposed and validated both numerically and experimentally. However, the is no consensus on how to approach the design of the frame members, questions remain regarding how best to design CRSBFs to prevent building collapse, and no experimental work has been done regarding how to connect the CRSBF to the rest of the structure to accommodate the rocking motion. Because the force limiting mechanism of a CRSBF is rocking only at the base of the frame, the frame member forces are greatly influenced by the higher-mode response, resulting in more complex methods to design the frame members. This thesis begins by outlining two new design procedures for the frame members in controlled rocking steel braced frames that target both simplicity and accuracy. The first is a dynamic procedure that requires a truncated response spectrum analysis on a model of the frame with modified boundary conditions to consider the rocking behaviour. The second is an equivalent static procedure that does not require any modifications to the elastic frame model, instead using theory-based lateral force distributions to consider the higher modes of the rocking structure. Neither method requires empirical calibration to estimate the forces at the target intensity. The base rocking joint design is generally in good agreement between the various research programs pioneering the development of the CRSBFs. However, the numerous parameters available to select during the design of the base rocking joint give designers an exceptional amount of control over the performance of the system, and little research is available on how best to select these parameters to target or minimise the probability of collapse for the building. This thesis presents a detailed numerical model to capture collapse of buildings… Advisors/Committee Members: Wiebe, Lydell, Civil Engineering.

▼ Thesis Abstract: Chapter I: Regional burden sharing of GHG mitigation policies – A Canadian perspective. The distribution of the burden of cost arising from the reduction of greenhouse gas (GHG) emissions is a contentious issue in policy discussions; more so among regional jurisdictions in the federalist countries with decentralized authorities over environmental regulations. In this setting, often the policy discussions are focused on the distribution of regional emission reduction targets that, in turn, entails negotiations over the distribution of the scarcity rents and the regional transfers of wealth. The allocation of regional emission entitlements is thus a key factor that could hinder the political feasibility of a national GHG mitigation policy. In this paper, we build a multi-region computable general equilibrium (CGE) model of the Canadian economy to assess the implications of different burden sharing rules governing the national GHG abatement policy with a cap-and-trade system of emission permits. In addition to assessing the impacts of traditional regional emissions allocation rules that involve intra-regional transfers of wealth, we consider a particular emission allocation that avoids such transfers, which may be a more palatable option given the context of likely fierce negotiations over the issue. Our results indicate to differing outcomes depending on the allocation policy in use. The CGE framework is also able to shed light on the transmission mechanisms that drive the results underlying the policy options. Chapter II: Endogenous technological change and emission allowances. Given the imminent threat of global warming due to GHG emissions, a number of emission mitigation policies have been proposed in the literature. However, they generally suffer from the classical equity-efficiency trade-off. High costs from equity concerns often render environmental policies politically unattractive and thus hard to implement. Recent advancement in the climate policy modeling literature that incorporates endogenous technological change (ETC) into the framework can potentially bring new insights into this debate. Using an inter-temporal, multi-sector CGE approach with ETC incorporated into the framework, this paper builds a model that focuses on the equity-efficiency debate for the policymakers. Canada is chosen as the country of investigation for this purpose. The paper provides a new welfare ranking of four permit allocation policies that address the equity-efficiency trade-off. In a second-best setting with pre-existing distortions, output-based allocation (OBA) of emission permits is compared to three other policy options: (i) an emissions trading system with grandfathered allocation (GFA), (ii) an auction permit trading system where permit revenue is recycled to lower payroll taxes (RPT), and (iii) a hybrid of OBA and R&D subsidy (O-R&D). We find that adapting OBA, as well as O-R&D, is welfare improving over GFA. The implicit output subsidy, entailed in the OBA policy, mitigates against the…
