▼ Carbonates may be incorporated in the mantle at collisional plate boundaries by many processes, including subduction of weathered oceanic lithosphere and fault-bounded tectonic slivers of seamounts. Once magnesite is formed in subducting slabs, it is likely to remain as an important carbon-bearing phase, as its stability extends over a wide range of mantle conditions. High-magnesium carbonates, including magnesite and dolomite, have been observed in ultra-deep metamorphic collisional terrains and in mantle xenoliths. Recent deformation experiments of magnesite indicate that it is weaker than mantle phases such as olivine and that it is likely to affect the geodynamics of subduction. Microstructures and lattice orientations of experimentally deformed samples have been investigated in this study, using optical and electron microscopes and electron backscatter diffraction. Microstructures of samples deformed at lower temperatures (400-600 ˚C), at strain rates of 10^-4-10^-6 s^-1 and an effective pressure of 900 MPa are dominated by undulose extinction, kink bands, and mechanical twins. At higher temperatures (>750 ˚C), microstructures include undulatory extinction and extensive dynamically recrystallized grains, subgrains, and core-and-mantle structures. Mechanical twins are not observed at these higher temperatures. External rotations of magnesite c- and a-axes show that dislocations glide on the c, r, and f planes by slip systems that are similar to those reported for calcite and dolomite. Additionally, magnesite mechanically twins on the e- and f-planes. The CRSS values for magnesite twins exceed 300 MPa, significantly greater than twinning CRSS reported for either calcite or dolomite. I propose that twinning CRSS in the carbonate system is controlled, not by crystal class or cationic ordering, but by cationic size, which affects CO3^2- anion-anion repulsion at twin boundaries. This hypothesis is consistent with lowest energy calcite twin modeling of Bruno et al. (2010). In a similar fashion to twinning, I predict that dislocation movement is also controlled by cation size. Lastly, I observe that this effect is not limited to carbonates. Cationic size may also affect CRSS values for twinning in oxides and the strength of olivine with different Fe and Mg contents deforming in the dislocation creep regime.

▼ Experiments were conducted in a Griggs-type deformation apparatus at high temperature and pressure to determine the effects of fluids on rock rheology. In the first suite of experiments, quartzite samples were deformed in the presence of aqueous and carbonic fluids to document how the addition of CO2 affects the strength of quartzite deforming by dislocation creep. My results document that the presence of CO2 can cause strengthening or weakening depending on the oxygen fugacity of the deformation environment, which changes the water fugacity. The results of these experiments highlight the importance of chemical environment for quartzite deforming by dislocation creep and suggest that local differences in oxygen fugacity, possibly due to changes in local mineral assemblages, can affect the deformation behavior of quartz by changing water fugacity in the presence of CO2. In the second suite of experiments, antigorite serpentinite was deformed within its stability field and where dehydration occurs to characterize its deformation behavior. The presence of a thin layer of ductily deforming antigorite has been suggested as the mechanism that allows for slab-wedge coupling in subduction zones. My experiments document that deformation localizes within the antigorite stability field, however the "effective" viscosity in the shear zones may be low enough to explain decoupling. Experiments conducted above the thermal stability of antigorite indicate that dehydration is associated with extreme weakening but not unstable behavior. My results suggest that weakening is due the generation of a pore fluid pressure at the onset of dehydration, which decreases the effective pressure. Sample strength may also be affected by the generation of porosity and fine-grained reaction products along grain boundaries. Experiments in which temperature was increased to cross the reaction temperature during deformation document rapid weakening that occurs over several minutes and is controlled by the ratio of ramp rate/strain rate. Strain rate stepping experiments both above and below the dehydration temperature document that antigorite is velocity strengthening, a behavior that inhibits earthquake nucleation. My results therefore suggest that antigorite dehydration does not directly lead to the generation of intermediate-depth earthquakes but may lead to slow slip events.

▼ This thesis documents a study of the high strain rate deformation behavior of Ni-containing steels of interest to the U.S. Navy for ship structures. A range of microstructures that resulted in different static mechanical properties in a family of Ni-containing steels was generated by modifying heat treatments for a given steel composition (10% Ni-0.1%C) and by modifying the steel composition in terms of Ni content (2.5%, 3.5%, 4.5%, 6.5% and 10%) as well as C (0.1% and 0.03%) content. The loss in strength from C decrease in the lower Ni versions was offset by adding Cu to produce precipitation hardening from the nanosize Cu precipitates. The influence of microstructure on the dynamic properties of these steels was studied through a combination of careful documentation of the initial microstructure, mechanical testing using the Kolsky compression bar set-up, and detailed post-deformation microstructure characterization. The dynamic deformation behavior of a steel with the composition 0.09%C-10.0%Ni-1.2%Mo-0.6%Mn-0.5%Cr-0.1%V (wt.%) was first examined in two different tempers. In the first case, the microstructure consisted of heavily dislocated martensite laths with a fine distribution of MC carbides. This microstructure was highly prone to shear localization in the strain rate regime 2 x 10 3 s -1 to 4 x 10 3 s -1 . The resulting adiabatic shear band, approximately 15 μm wide, consisted of submicron equiaxed grains composed of a mixture of fcc and bcc phases thought to be austenite and ferrite/martensite.In the second case, the tempered microstructure consisted of martensite laths although the dislocation density appeared lower; in addition to coarse MC carbides, M 2 C carbides and austenite islands were noted. At comparable strain rates, the steel was more resistant to localization and a well-developed shear band was not obtained; incorporating a notch in the specimen however facilitated the formation of a shear band. The microstructure within the band was again composed of equiaxed grains but diffraction patterns did not show the presence of the fcc phase, implying its transformation during deformation to bcc ferrite/martensite. This phase transformation of austenite to martensite may be responsible for the enhanced resistance to shear localization. This finding was followed by a methodical study to evaluate the role of precipitated austenite content, composition and size distribution on xvi discouraging shear localization. Mössbauer spectroscopy was used to determine austenite content in the heat-treated steels. Results confirmed that when the austenite content was in excess of 5 volume percent, shear localization could be postponed. For similar volume fractions that showed enhancements in shear localization resistance, tempering at a lower temperature resulted in less of a loss in static strength while displaying enhanced ballistic resistance. When lower levels of Ni were incorporated in the alloy, for example 2.5% Ni or 3.5% Ni instead of 10% Ni, the shear localization resistance improved but the improvement… Advisors/Committee Members: kumar, sharvan (Director), Guduru, Pradeep (Reader), Briant, Clyde (Reader).

The Coptic cemetery in Manshiyet Nasser, is the final result of a process that includes mapping, "transcription" of these diagrams and design according to certain principles defined during the process. The site for the mapping was Manshiyet Nasser /Garbage city, where the garbage collectors of Cairo are settled. The reason behind the choice, is that this place offers an opportunity to study how the garbage occupies public space in different configurations and what kind of space is created between the elements that are part of. The final product of mapping is a series of diagrams that depict a deformed grid. The degree of deformation varies, according to the voids created between the elements on the picture /the front view of stacks. The quality on which the interest is focused, are the dense and sparse areas that are created by deformation. The sucession of dense and sparse areas is becoming the main principle of the design. Other key words of the design are :altered landscape and bridging of different levels. The last ones were influential so as the cliff to be the site of intervention. The program is related to the notions of : layered structure, repetition of units, connections-disconnections. At the same time, the cemetery as proposal, might be a solution for the current problematic situation; the Coptics that live in the Garbage City have to travel even for 55km for visiting the cemeteries. The final design concerns a structure that creates a new border between the cliff and the public space. It may be described as a building-landscape (or landscape building?) for the reason that there is no interior or exterior in the common sense -which is the case for a building, however is formed by elements that are common in buildings such as slabs and walls. The structure consists of precast concrete elements. The graves are developed verticaly, in combination with plants on top of each volume. The solid parts of the structure -that are the graves, are filled with soil, which is also a necessary condition according to the Coptics' tradition, but also plays a role in the decomposition process. Thus, this design proposal preserves the positive qualities of the traditional cemetery setting-which is outside the city and at the same time has a closer relation to urban life.

▼ Ce travail vise à mieux comprendre les interactions entre couplage, glissement lent et rupture sismique en contexte de subduction. L’objet d’étude est la subduction Nord Chili–Sud Pérou, qui a été reconnue comme une lacune sismique et qui a fait l’objet d’un important effort international d’instrumentation géophysique. Cette zone a été affectée par tremblements de terre qui ont été bien enregistrés, ce qui en fait une cible bien adaptée pour étudier les mécanismes de préparation des grands séismes de subduction, et le lien entre couplage, glissements lents et rupture sismique.Les 65 stations GPS installées dans la zone ont été traitées en doubles différences avec le logiciel GAMIT-GLOBK sur la période 2000-2014. Les séries temporelles de position obtenues ont été analysées et les déplacements associés aux différentes phases du cycle sismique et aux mouvements saisonniers ont été modélisés.L’analyse des tendances dans les séries temporelles GPS ont permis de mettre en évidence un changement de vitesse intersismique avant et après le séisme en slab-pull de Tarapacà de juin 2005, dans la région qui a été rompue par le séisme d’interface d’Iquique en 2014. Ce changement de vitesse est associé à un changement de taux de sismicité superficielle et profonde. Le déclustering du catalogue sismique indique que ce changement de taux, affecte aussi la sismicité de fond, caractéristique du taux de chargement. Nous avons pu mettre en évidence que des interactions existent entre sismicité profonde et superficielle, et pourraient jouer un rôle important dans la préparation des grands séismes d’interface. A plus courte échelle de temps, les séries temporelles montre un autre changement de vitesse 8 mois avant le séisme d’Iquique. La modélisation indique que ce changement correspond à un glissement lent de Mw 6.5, essentiellement asismique, correspondant à la phase de nucléation long-terme de ce tremblement de terre.Nous avons également analysé les variations court terme dans les signaux non-modélisés des séries temporelles GPS, qui ont permis d’identifier, grâce à une méthode de Template Matching 48 petits événements de glissement lent pendant la période de chargement intersismique. Ces événements sont basés pour leur grande majorité en dessous de la zone sismogénique dans des zones de couplage très faible, ou de couplage intermédiaire, indiquant que le glissement se fait par relâchements successifs.

Cell deformability is being recognized as an easily measurable indicator to differentiate different types of cells and detect diseased cells. A recent promising and advantageous technique to assess cell deformability is the cross-channel microfluidic deformability cytometry (DC). It uses a stretching extensional flow, in which each time an individual cell undergoes deformation. Using our three-dimensional computational algorithm for multiphase viscoelastic flow, known as VECAM, this study focuses on modeling the deformation of living cells in such microfluidic channels. Through the computational simulations, we first identified the central extensional flow region in the cross section of the channel, where cells are stretched due to mostly fluid momentum and resulting normal stresses. Our simulation data indicate that the range of deformability indices observed for human cells in DC experiments (from 1.5 to 2.3) corresponds to the range of cell elasticities from 3,000 to 15,000 Pa. We have also showed that both cell size and cortical tension have a much less effect on cell deformability than cell elasticity. The study further shows the cell oscillation in the extensional flow region caused by pressure imbalance in DC experiments does not affect much how long cell stays in this region and has a very limited impact on the measured cell deformability index. Finally, our study shows offset in both Y and Z directions can alter the results of the deformability measurement in a significant way. Our fully three-dimensional parallel computational algorithm is proven to realistically simulate cell movement and deformation in the cross-channel deformability cytometry. With the acquired simulation results, the computational study provides helpful insights and future guidance that are otherwise impossible to be obtained from the experimental data to the cytometry experiments.

▼ Geodetic Deformation Monitoring (GDM) plays a vital role in project safety and management. Geodetic measurements on dams are done to monitor change and rate of change in order to ensure safety. Kariba Dam suffers normal stresses, and strains mainly from temperature and hydrostatic pressure seasonal changes. These loads deflect the dam upstream/downstream in summer and winter, respectively. The deflections are currently monitored using a traditional deformation monitoring system by Zambezi River Authority (ZRA). However, more unexpected factors which were not catered for at design stage have rendered the traditional methods obsolete. These unexpected factors are: Reservoir Induced Seismicity (RIS), plunge pool scouring, Alkali Aggregate Reaction (AAR), landslide and earth-work vibrations. Thus, in this study, the dam was assessed to have new deformation patterns: Clockwise (southward) horizontal rotation of the north abutment, tangential movements of the dam northwards, increased upstream/upward swelling of the dam crest, and southward vertical rotation of the south and north bank . Due to the above deflections, the Kariba Dam arch has lost its original shape, with the arch ends buckling more than the spillway section. Human-related errors may worsen these deformations. The vertical and horizontal rotational tendencies resulted from anchor cables and landslide moments of forces on the south bank. AAR effect was analyzed as being of less concern because past findings proved it’s subsiding. Poor geology destabilized the control points, thus rendering the classical monitoring system less accurate. To address the new deformations, a real-time, automated GNSS/LPS Online-based Control and Alarm System (GOCA) was designed for an early detection, alerting of landslide and its effects on the dam to classified users. This system applies GNSS and classical Local Positioning Sensors (LPS) such as Total Stations, and geotechnical instruments. It was recommended that prism array be installed urgently for use even under the classical methods for more deformation detection. This research has explained the puzzling new dam behaviour and substantiated the effects of the landslide which might have been worsened by earth work activities in the area with poor geology. Hence this research formed a basis for future studies and monitoring system improvements at the Kariba Dam through easy-to-understand analysis and visualizations of concepts and past deformation data presented mainly in form of tables by ZRA. The analysis included computations of rates of change of current deformations compared to the previous. The past and current deformation results were visualized in form of drawings and illustrations which helped link landslide forces to new dam deformations.

▼ PROTEROZOIC ASSEMBLY OF NORTH AMERICA: INSIGHT FROM THE INTERACTIONS OF DEFORMATION, METAMORPHISM AND MAGMATISM IN THE SOUTHWESTERN UNITED STATES Robert Alexander Hunter, Ph. D. Cornell University One of the major goals of the geoscience community is to develop an accurate tectonic history of North America. Understanding how our continent evolved through time has numerous implications for our ability to develop accurate models of the tectonic evolution of continents - how they form, deform, and break. The interactions of deformation, metamorphism, and plutonism, three fundamental geological processes at work throughout the evolution of continents, record information that can be used to better understand the mechanisms and events that have shaped our continent. This dissertation employs metamorphic petrology, structural geology, geochemistry and geothermobarometry to interrogate the interactions of deformation, metamorphism and plutonism on multiple scales across the southwest United States. On a microscope scale, this dissertation shows that deformation and metamorphism can work in a positive feedback loop, facilitated by solution mass transfer, to localize both deformation and metamorphism, producing areas of high strain that have more closely approached metamorphic equilibrium. This result informs our understanding of crustal behavior at mid-crustal depths during orogenesis. On the mountain range scale, this dissertation combines petrographic analysis, structural geology, geochemistry and geothermobarometry to show that metamorphism in the Tusas and Picuris Mountains of northern New Mexico is consistent with one metamorphic event following a pressure-temperature-time trajectory consistent with progressive loading during the formation of a fold and thrust belt. This result informs our understanding of the tectonic history of North America, and has implications for the petrogenesis of aluminosilicate triple-point rocks in the region. Finally, on a continental scale, this dissertation uses previously published geochronologic data to identify spatial patterns in the age of igneous bodies across the southwest United States. These results were used to characterize mesoproterozoic tectonism and develop a model for melt production of these plutons. This result informs not only our understanding of crustal growth and rejuvenation during orogeny, but also provides a comprehensive dataset and novel approach that may both be employed in future research.

▼ In shape modeling applications, \emph{deformation} is the process of applying a continuous, non-affine transformation to a shape. The definition of the deformation should be independent of the representation of the shape. In practice, the shape is often represented by its boundary, which is defined by a set of vertices and by connectivity information. The transformation is often applied to these points. A deformation algorithm takes the orginal shape and designer's choices as inputs, and outputs the deformed shape. This dissertation dedicates to introducing \emph{spine-based deformation}: Any distortion to the shape is controlled by a low dimensional proxy, which is a spine curve or surface. Considering a sometimes important constraint to preserve the shape's volume during deformation, this thesis addresses a suite of problems in spine-based deformation with local volume preservation, meaning that the volume of any subset of the shape is preserved. Although our deformation model may be applied to the control points or vertices of a surface model that is not a water tight boundary of a solid, in this thesis, the term shape will refer to a solid model which has a clearly defined interior and volume. Previously proposed local or global volume compensation techniques are typically based on iterations that introduce a complexity bilinear in the numbers of vertices and iterations. we present a family of closed-form solutions for shape deformation with mathematically exact local volume preservation, and demonstrate their power in the context of interactive bending, rotating, sliding or stretching a 2D or 3D shape. The overall complexity is linear in the number of vertices. Proposed spine-based deformation framework adopts the following assumptions in geometric modeling: – When the spine is a curve, a plane normal to the spine curve remains normal to the spine curve after deformation. The parameter associated with the point at which the plane intersects the curve is unchanged. – When the spine is a surface, a line normal to the spine surface remains normal to the spine surface after deformation. The parameters associated with the point at which the line intersecting the plane remain unchanged. With these assumptions, we compute the closed-form formulation for the deformation that guarantees local volume preservation and is expressed using real roots of low degree polynomials and simple point and vector expressions. Due to its simplicity, our solution may be used to deform complex models in realtime during interactive manipulation or during animation, where the behavior of the spine has been designed or is computed in realtime through simulation.

▼ Gravitational removal of the dense lower lithosphere is proposed to be a fundamental process in continental tectonics. This has been used to explain seismological observations of an abnormally thin lithosphere beneath some regions and evidence for detached lithospheric materials at 100-200 km depth. In addition, geochemical arguments suggest that a significant portion of the lower lithosphere may have been recycled into the deeper mantle. The removal process should significantly affect the overlying crust, causing transient uplift/subsidence, crustal contraction/extension and pulses of volcanism. As removal can occur in continental plate interiors, it may provide an explanation of areas of anomalous intraplate deformation that can not be readily linked to tectonic processes. This thesis uses two-dimensional thermal-mechanical numerical models to explore the surface deflection and magmatism induced by gravitational lithosphere removal. Removal is widely believed to be associated with surface subsidence and widespread asthenospheric magmatism. However, the models show that the surface expression depends strongly on the thermal and rheological structure of the lithosphere. If the crust is weak, the descending dense lithosphere induces lateral crustal flow, leading to crustal thickening and surface uplift. Crustal flow in a mid-crustal channel will smooth the surface subsidence caused by the dense lithosphere; crustal flow in a lower-crust channel can cause the surface to invert to become a topographic high. Magmatism caused by lithosphere removal depends on the removal style and the initial thermal structure of lithosphere. During a Rayleigh-Taylor instability (drip), three types of magmas are found: (1) for a hot lithosphere (e.g., back arc), the foundering lithosphere can melt as it is descends and the asthenosphere can undergo decompression melting as it upwells to replace the removed lithosphere; (2) for a warm lithosphere (e.g., average Phanerozoic lithosphere), only asthenospheric melt is predicted; (3) for a cold and thick lithosphere (e.g., craton), no magmas are generated during removal. If removal occurs through delamination, the dense mantle lithosphere rapidly peels along the Moho and sinks into the deep mantle before it can melt. However, significant decompression melting of the asthenosphere may occur as it upwells to the base of crust. Delamination is associated with an asymmetric surface signature, where crustal deformation and magmatism migrate with the detachment hinge. In a Rayleigh-Taylor instability, the deformation and magmatism are symmetric. Observational data from a number of regions (e.g., southern Sierra Nevada in North America, Puna plateau in the central Andes, and Tibet in western China) are consistent with the numerical models, suggesting that intracontinental deformation and magmatism in these areas are related to lithosphere removal.

▼ The primary subject of this thesis is the evaluation of pipeline performance during earthquakes through analytical and experimental studies, spatial analysis, and probabilistic methodologies. Permanent ground deformations caused by liquefaction are also addressed through spatial and statistical analysis, and are compared to foundation deformations caused by liquefaction effects estimated through building damage surveys. This thesis starts with a comprehensive analytical and experimental assessment of segmented pipeline response to transient ground deformation before and after rehabilitation with in situ lining technologies. The different modes of segmented pipeline deformation caused by seismic wave propagation are investigated through finite element analyses to show that the most prominent form of deformation at weak pipeline joints and circumferential pipe cracks are in the axial direction. They exceed the levels of all other forms of pipeline deformation by several orders of magnitude. Nonaxial deformations have negligible effects on pipeline performance under seismic body wave propagation. Pipeline performance after rehabilitation with in situ linings is studied through large-scale testing and the effectiveness of in situ lining technology for seismic retrofit of critical lifelines is evaluated. Pipeline performance during earthquakes is also investigated through spatial analysis of the Christchurch water distribution system response to transient and permanent ground deformations during the 22 February 2011 Christchurch earthquake, New Zealand (NZ). Repair regressions for different pipe types are developed using spatial data sets that are unique in size and complexity, including dense array ground motion records, detailed mapping of areas affected by soil liquefaction, as well as spatial data sets for the water distribution system, geocoded repair records, and high resolution Light Detection and Ranging (LiDAR) measurements of vertical and horizontal movements. This study expands on previous work in several important ways, and provides a detailed framework of the analytical processes for repair regressions that assists in future investigations with data of similar size and complexity. A probabilistic model is presented in which the expected value of the ground strain in the axial pipeline direction within a strain field is calculated by assuming that pipeline orientation with respect to the strain field is uniformly distributed and by accounting for possible differences in tensile and compressive strains with a weighting factor. The proposed methodology is applied in regression analysis of pipeline damage caused by lateral ground strains during the 22 February 2011 Christchurch earthquake, NZ, and can be used for future investigations to improve the assessment of ground strains affecting segmented pipelines. Permanent ground deformation during the 2010-2011 Canterbury Earthquake Sequence, NZ, is evaluated through statistical analysis of vertical and lateral ground displacements, as well as differential vertical… Advisors/Committee Members: O'Rourke, Thomas Denis (chair), Grigoriu, Mircea Dan (committee member), Phoenix, Stuart Leigh (committee member), Aref, Amjad J (committee member).

▼ The use of clumped isotope analysis in calcite is a rapidly developing and powerful technique for paleothermometry studies in tectonics and environmental sciences. For analysis of isotopes in deformed rocks, there is uncertainty if the deformation of the calcite can reset clumped isotope concentrations, which limits the utility of the method. The goal of this research is to help determine if some typical deformation processes, specifically plastic deformation of calcite at low temperatures (˂200 C), can affect clumped isotope concentrations. Seven cores of calcite are deformed experimentally at strain rates 2-4.2x10⁻⁵ s⁻¹ , temperatures from 20 – 400 C, at confining pressure of 150-200 MPa, and to strains of 10-25%. The cores are taken from parent crystals in four different orientations relative to the crystallographic directions of calcite in order to induce different types of deformation. The deformed samples were studied using optical microscopy and electron backscatter diffraction microscopy techniques to identify the types of plastic deformation that operated in each test. Both mechanical e-twinning and r- and r+ slip were successfully activated, and to varying degrees, in the sample suite. Yield strengths observed in the experiments agree well with that expected (based on previous work) for the twin and slip mechanisms identified through microscopy. On the basis of the outcomes of this research, clumped isotope measurements of the parent crystals and the deformed samples will determine if, and which deformation processes affect isotope concentrations. If isotope concentrations remain unchanged by deformation, then the reliability of clumped isotope analysis in deformed rocks will be assured. If deformation resets clumped isotope concentrations, then with further research the method holds great promise to determine the temperature at the time of deformation, which would be a unique capability.

▼ This study is conducted to analyze the deformation pattern at a locality in the central part of Afar, northeast of Semera town, within the triple junction that is formed by the Arabian, Nubian and Somalian diverging plates. The study area is bordered by Manda Harraro rift in the northwest and Tendaho rift in the south. The region is one of the tectonically active areas in the world, where the episode of plate movement resulted in seafloor spreading that causes the earth‟s surface to deform in the form of surface cracking, sliding and faulting. Presently this dynamic process of earth‟s deformation in space and time can be accurately detected by satellite space geodetic observations. This study used Global Positioning System (GPS) and Interferometric Synthetic Aperture Radar (InSAR) to study earth surface deformation. InSAR data from Envisat, image mode, with track 028 ascending and track 278 descending is used to detect surface deformation over the study area. To constrain the InSAR observations, continuously recorded GPS data obtained from DASM (2007-2012) and DASA (2008-2009) are used to investigate possible surface deformation changes in the area. The three dimensional position coordinates acquired from the DASM and DASA GPS stations over their period of observations have suggested a ground surface deformation rate of 48.5+0.2mm/yr North, 39.5+0.2mm/yr East and -9.5+0.7mm/yr Up; and 27.8+0.4mm/yr North, 43.9+0.5mm/yr East and -21.8+1.4mm/yr Up for DASM and DASA GPS stations, respectively in an absolute sense. The Up component of DASM shows two characteristics, 2.8 mm/yr up to doy 150, 2008 and -25mm/yr afterwards. The DASA shows also -10mm/yr up to doy 147, 2008 and -29mm/yr afterwards. The InSAR time-series shows -44mm/yr Line of Sight (LOS) rate in both track. The correlation between the DASM GPS and track 028 is 0.75 and it has a correlation of 0.79 with track 278. Generally, the result from this investigation suggested that there is an active subsidence in the area which needs further attention. Advisors/Committee Members: Dr. Elias Lewi (advisor).

The work in this thesis focuses on the martensitic steel known as P91. In this work the mechanical response of the material was examined through nite element material modelling and the results validated through experimental methods. The primary goal of this research is (i) to accurately represent the material response of P91 at a range of temperatures, and (ii) to validate the material model through the analysis of crystallographic orientations on the micro scale. Uniaxial tensile tests were conducted using parent metal, weld metal and cross weld specimens that had been extracted from a functioning power plant with 20,000 hours of service. The results of the parent P91 were consistent with other literature results in the case of yield strength and elastic modulus. However the ductility of the steel was reduced after experiencing service. The weld results showed a con- siderable increase in yield strength when directly compared to P91 parent steel. The uniaxial high temperature data was used to calibrate a crystal plasticity material model based on a ow rule. The ow rule is a slip- system based crystal plasticity model used to represent the material deformation at the micro scale. Specimen level modelling also took place, where the material model was represented by the uniaxial data provided by the experimental testing in an isotropic elastic plastic model formulation. Microscopy was undertaken to investigate the microstructure of P91. Scanning electron microscopy (SEM) was utilised as well as elec- tron backscatter di raction (EBSD) to characterise the complex grain structure associated with martensitic steels. This crystallographic data was utilised in the modelling of the micro scale analysis of the steel. Crystal deformation o ered a means of evaluating how well the ma- terial model predicts the change in orientations. It was found that in general, the material model gave a good prediction of the change in crystallographic orientations for both the room temperature and high temperature cases.
