▼ This dissertation contains the results from an experimental study, numerical, and analytical study conducted on quasi-isotropic carbon fiber laminates containing a center hole (notch) subjected to constant amplitude tension-tension fatigue loading in order to investigate the effect of fatigue damage development on the residual properties. Quasi-static tests were initially performed on notched composites using digital image correlation (DIC) to determine the strain profiles at selected transverse sections of the outer ply of the laminates and the static strength of the laminates. Subsequently, tension-tension fatigue tests were carried out at 70%, 75% and 80% of the nominal static failure load. A finite element model was developed using Abaqus and Digimat in which Digimat was used to implement the damage evolution model via a user-defined material subroutine. Damage initiation has been assessed using Hashin's failure criteria and the Matzenmiller model was adopted for damage evolution. A second finite element model was developed using Abaqus and Autodesk Simulation Composite Analysis (ASCA) in which ASCA was used to implement the user-material subroutine. The subroutine includes a failure initiation criterion based upon multi-continuum theory (MCT) and an energy-based damage evolution law. Numerical and experimental strain results were presented and compared for different section lines on the outer surface of the laminate at different loading stages. Additionally, the experimentally measured notched composite strength was compared with the predictions from the finite element solutions. These results are used as baseline for subsequent comparison with strain profiles obtained using DIC for specimens fatigued at different stress levels and fatigue lifetime fractions. The results showed a significant effect of fatigue damage development on strain redistribution even at early stages of fatigue. The results also showed the capability of DIC technique to identify damage initiation and its location. Furthermore, X-ray computed tomography (CT) was used to examine the sequence of damage development throughout the fatigue lifetime and to connect the observed damage mechanisms with the occurred change of strain profiles. Experimental vibrational modal analysis tests were also conducted to assess the effect of fatigue damage on the residual frequency responses (RFRs). Vibrational measurements were initially performed on pristine notched composites. The results are used as baseline for subsequent comparison with strain profiles obtained with DIC. Finite element models based on the classical plate theory (Kirchhoff) and the shear deformable theory (Mindlin) within the framework of equivalent single-layer and layer-wise concepts as well as the three-dimensional theory of elasticity are developed to predict the natural frequencies of non-fatigued specimen. These models are implemented using the finite element software, Abaqus, to determine the natural frequencies and the corresponding mode shapes. In addition, an analytical model… Advisors/Committee Members: Case, Scott W. (committeechair), Ragab, Saad A. (committee member), Lattimer, Brian Y. (committee member), Cramer, Mark S.

▼ The serious pollution problem caused by transportation can cause critical environmental effect such as global warming. This has drawn attention towards lighter materials for use in the transportation industry. Magnesium as the lightest structural metal has been very attractive for both researchers and industry. Use of magnesium in the transportation industry for non-structural components goes back to the 1930’s, but recently it has been under investigation for load bearing component, in which they are exposed to cyclic loading and therefore are subject to fatigue failure. Cold expansion is one of the well-known techniques for enhancing the fatigue properties notched specimen, which is used widely in aerospace. For the first time, the feasibility of performing cold expansion on commercial AZ31B magnesium sheet is studied in this research and presented herein. Optimizing the process from the fatigue point of view is done. In order to model the process, a numerical method called variable material property (VMP), with capability of considering actual material behavior, and a finite element software, ABAQUS, were used. To verify these models, two experimental measurements have been done, using digital image correlation (DIC) technique to capture the radial displacement around the notch during loading, and residual stress measurement by X-ray diffraction method after unloading. To obtain the material behavior needed in VMP method, tension-compression and compression-tension loading-unloading tests were performed on the material. It was shown that split sleeve cold expansion can significantly improve the fatigue life, by postponing crack initiation and decreasing the rate of crack propagation, compared with as-received notched sample. The fatigue life improvement factor gets higher in high cycle regime. In low cycle fatigue, the improvement factor is roughly 2.5x, while in high cycle it gets up to an order of magnitude. It was also shown that the optimum degree of cold expansion percentage was 5 % and 6% for 4 mm and 3.18 mm sheet, respectively. The effect of cold expansion on crack initiation and propagation life was examined using DIC technique. Fractography revealed that on untreated samples, crack initiation occurred on the notch surface, while in the samples with the optimum degree of cold expansion the crack initiation occurs internally and away from the notch surface. This has been attributed to the residual stresses induced in cold expansion process.

Cette thèse s’intéresse à l’étude l’effet de la corrosion sur les propriétés mécaniques des armatures corrodées et les performances mécaniques résiduelles des poutres corrodées. L’étude est basée sur deux poutres corrodées notées B2CL2 et B2CL3, conservées respectivement 26 ans et 28 ans en ambiance saline. Deux poutres non corrodées B2T2 et B2T3 conservées en conditions ambiantes ont également été testés afin d’identifier l'effet de la corrosion indépendamment du vieillissement.Les propriétés mécaniques des armatures corrodées ont été étudiées par des essais de traction.La limite d'élasticité et résistance à la rupture ont été étudiées sur la base de la section transversale résiduelle évaluée par perte de masse. Les résultats ont montré que les effets de la corrosion sur la diminution ductilité étaient très importants. La forme de la section transversale résiduelle apparait comme étant un paramètre essentiel affectant la ductilité de l'armature.Les performances résiduelles en flexion des poutres corrodées ont été étudiées. Les résultats montrent que la corrosion réduit la capacité portante et de façon plus significative, la flèche maximale à rupture en raison d’un changement de mode de rupture. La diminution de la charge de plasticité apparait en relation avec la perte de section d’acier tendu due à la corrosion Des poutres de portées courtes ont été réalisées à partir des poutres corrodées après les essais de flexion. Les tests mécaniques ont été effectués en flexion pour vérifier la réponse des poutres courtes corrodées. Les poutres courtes corrodées ont péri en flexion avec une bonne ductilité tandis que les poutres courtes non corrodées ont péri comme prévu en cisaillement suivant un mode de rupture fragile, qui a montré que la corrosion de l'armature pouvait modifier les modes de défaillance.Les produits de corrosion ont été recueillis à partir de l'armature corrodée de B2Cl3. Des expériences XRD et TG ont été menées afin d'identifier la composition des produits de corrosion. Le coefficient d'expansion des produits de corrosion a été déduit, ce qui pourrait être utile pour les recherches futures concernant le mécanisme de fissuration du béton d'enrobage.

The experiments were based on two corroded beams named B2Cl2 and B2Cl3, with a corroded age of 26 years and 28 years respectively. Two noncorroded beams B2T2 and B2T3 which were cast in the same condition and same time were also tested in order to make clear the corrosion effect.The mechanical properties of the corroded reinforcement were investigated by the tensiontests. The yield strength and ultimate strength were studied based on the residual gravimetrical cross-section. The results found that the impact of corrosion on the ductility was more significant than that of the strength. The shape of residual cross-section was considered to be in deep relationships with the ductility of the reinforcement.The flexural performances of the…

▼ Terrorists usually target high occupancy iconic and public buildings using vehicle borne incendiary devices in order to claim a maximum number of lives and cause extensive damage to public property. While initial casualties are due to direct shock by the explosion, collapse of structural elements may extensively increase the total figure. Most of these buildings have been or are built without consideration of their vulnerability to such events. Therefore, the vulnerability and residual capacity assessment of buildings to deliberately exploded bombs is important to provide mitigation strategies to protect the buildings' occupants and the property. Explosive loads and their effects on a building have therefore attracted significant attention in the recent past. Comprehensive and economical design strategies must be developed for future construction. This research investigates the response and damage of reinforced concrete (RC) framed buildings together with their load bearing key structural components to a near field blast event. Finite element method (FEM) based analysis was used to investigate the structural framing system and components for global stability, followed by a rigorous analysis of key structural components for damage evaluation using the codes SAP2000 and LS DYNA respectively. The research involved four important areas in structural engineering. They are blast load determination, numerical modelling with FEM techniques, material performance under high strain rate and non-linear dynamic structural analysis. The response and damage of a RC framed building for different blast load scenarios were investigated. The blast influence region for a two dimensional RC frame was investigated for different load conditions and identified the critical region for each loading case. Two types of design methods are recommended for RC columns to provide superior residual capacities. They are RC columns detailing with multi-layer steel reinforcement cages and a composite columns including a central structural steel core. These are to provide post blast gravity load resisting capacity compared to typical RC column against a catastrophic collapse. Overall, this research broadens the current knowledge of blast and residual capacity analysis of RC framed structures and recommends methods to evaluate and mitigate blast impact on key elements of multi-storey buildings.

Subjects/Keywords: blast analysis, dynamic analysis, numerical simulation, reinforced concrete framed buildings, global and local analysis, post blast damage analysis, residual capacity, damage index, finite element method, linear and non-linear structural analysis; concrete steel composite column, blast mitigation design methods, blast influence region, near field blast events, multi-layer reinforcement

Para muitos componentes e estruturas de engenharia a determinação precisa do estado de tensões residuais presente é de fundamental importância para a avaliação de sua integridade estrutural. O método do furo cego (MFC) é um dos métodos mais difundidos para a medição de tensões residuais, no entanto, por se tratar de um ensaio relativamente complexo, a determinação da sua incerteza de medição apresenta uma série de dificuldades, as quais se refletem na inexistência de estudos na literatura que abordem esse assunto de forma completa. Este trabalho tem como objetivo a determinação da incerteza de medição do MFC englobando todas as fontes de incerteza em potencial do método. Para tanto, foi elaborado um procedimento envolvendo a determinação e caracterização das fontes de incerteza tanto na parte experimental como no tratamento matemático dos dados. A partir da caracterização das fontes de incerteza detectou-se como fator principal na determinação da incerteza o erro do operador, que foi possível através do desvio de repetitividade. A fonte de incerteza devido ao erro do operador foi a de determinação mais complexa e envolveu o projeto e a construção de uma máquina especialmente desenvolvida para a aplicação de um estado de tensões homogêneo e que permitisse medir com precisão as tensões residuais com o método do furo cego. Técnicas de medição de tensões residuais por difração de raios-X e monitoramento de tensão com extensometria de resistência elétrica foram utilizadas para a verificação da homogeneidade das tensões nas amostras. A metodologia se mostrou adequada, conduzindo a resultados que permitiram determinar com sucesso a incerteza de medição através de planilhas eletrônicas.

The characterization of the residual stress state of engineering components and structures is of fundamental importance for assessments of their structural integrity. The hole drilling method is one of the most commonly used methods; however, due to its relative complexity, quantifying its measurement uncertainties is not straightforward. It is a semi-destructive method, which means that multiple measurements cannot be repeated in a same location, and stress distributions mean that it is difficult to guarantee that a number of points in the same state will be available in a given volume. This study suggests a global uncertainty measurement which includes a study of repeatability related to the operator. This is thought to be novel in the existing literature. For this, a standard sample and a machine which guarantees a homogeneous stress distribution in the sample were developed. To ensure the homogeneity of the stresses, x-ray diffraction measurements were performed. The results obtained show good repeatability for different operators and good results for the uncertainty of measurements for the method.

▼ A multiscale computational framework for multiphase composites considering damage is developed in this research. In micro-scale, micromechanics based homogenization methods are used to estimate effective elastic moduli of graded Ti_(2)AlC/Al composites (GCMeCs) considering existence of damage (micro-voids). Then, in macro-scale, these properties are implemented in finite element model by using user material subroutine (UMAT) in Abaqus for numerical analysis of plate. In meso-scale, detailed 3D RVEs are created based on the microstructure of composites. Effective thermal and elastic properties are obtained from the corresponding FE models of 3D RVEs and compared with experimental results and micromechanics based homogenization methods. Two constitutive models are used to model plastic-damage behavior of two IPCs regarding their different material properties of constituent phases: (1) Due to the ductile properties of constituent phases for stainless-steel/bronze IPCs, a widely used porous plasticity constitutive model, Gurson-Tvergaard-Needleman (GTN) model, is adopted to investigate elastoplastic-damage behavior of stainless-steel/bronze IPCs. (2) For porous Ti_(2)AlC, a continuum damage mechanics (CDM) based plastic-damage coupled constitutive model is used to study damage evolution in porous Ti_(2)AlC, which can take distinct tensile and compressive inelastic behaviors of Ti_(2)AlC into consideration. From the simulation results of FE models of 3D RVEs, it is found that: Porosity and interfacial layer with low effective thermal conductivity lowers the overall heat flux flowing through NiTi/Ti_(3)SiC_(2) IPC. The existence of thermal residual stress within stainless-steel/bronze IPCs leads to plastic deformation, especially in bronze phase, which further results in reduction of apparent moduli subjected to uniaxial tension. Nucleation of the new voids, which occurs at the second-phase particles by decohesion of the particle-matrix interface, has the main contribution to the overall damage. For porous Ti_(2)AlC with aligned ellipsoid-like pores, tensile stress plays a very important role in local damage of porous Ti_(2)AlC due to the relatively low tensile strength and brittle-like tensile behavior of dense Ti_(2)AlC. Different than typical porous ceramic, porous Ti_(2)AlC fails in a quasi-brittle manner even with 30-40 vol. % porosity. The transversely isotropic material system has higher compressive strength in transverse direction than that in longitudinal direction. Advisors/Committee Members: Reddy, J.N.

▼ Structural health monitoring systems have a great potential for cost saving and safety improvement in different types of structures. One of the most important tasks of these systems is to identify damage at an early stage of its development. A variety of methods may be used to identify, locate, or quantify the extent of damage or fault in a structural or mechanical component. However, the preferable method is the one which maximises the probability of detecting the flaw, while also considering feasibility of in-situ testing, ease of use and economic factors.Cracks are one of the common defects in structural components that may ultimately lead to failure of structures if not detected. The presence of cracks in a structure brings about local variations in the stiffness of the structure. These variations cause the dynamic behaviour of the cracked structure to be different from that of a healthy one. Vibration-based damage detection methods have attracted considerable attention over the past few decades. These methods generally use changes to the physical properties of structures for the purpose of crack detection. In this thesis, two new vibration-based methods have been developed for damage detection in beam-like and rotor-type structures. The first method performs the entire signal processing required for crack detection in time domain. It is based on assessing the normality of vibration responses using the normal probability plot (NPP). The amount of deviation between the actual and normal distribution of measured vibration responses was calculated along the length of the structure to localise the crack.The second proposed method converts the vibration responses into frequency domain for further processing. Excitation of the cracked structure at a given frequency always generates higher harmonic components of the exciting frequency due to the breathing of the crack. This method uses the operational deflection shape of the structure at the exciting frequency and its higher harmonics to identify the crack location.Avoiding complicated signal processing in frequency domain is the main advantage of the first method. However, more precise identification of crack locations can be obtained through the second method. Generally, both methods have the advantage of being easy, reference-free and applicable to in-situ testing for any structure. The concept and computational approach of both methods along with their validations through numerical and experimental examples have been presented. Moreover, different input excitations have been used to evaluate the capability of the developed methods in detecting the crack location(s).

▼ Foreign object damage (FOD) refers to the damage that generally takes place in aero engine fans and compressor blades, due to the ingestion of hard particles/debris during aeroplane take-off, taxiing, or landing. Such damage can reduce the fatigue life expectancy of the turbine engine components by 50%. Residual stresses and small microcracks induced by the high speed FOD impacts are two root causes that result in premature failure of these components. One way to mitigate the FOD related fatigue failure is to induce deep compressive residual stress into the surface. Among the available techniques that can induce such compressive residual stress, laser shock peening (LSP) has been found to be beneficial in improving the fatigue strength. In this study aerofoil-shaped Ti-6Al-4V leading edge specimens were laser shock peened. Subsequently, FOD was introduced onto the leading edge specimen through ballistic impacts of a cube edge at angles of 0° and 45° to the leading edge. The effect of foreign object damage (FOD) on the pre-existing compressive residual stress field associated with the laser shock peening (LSP), and its change upon solely low cycle fatigue (LCF) as well as combined low and high cycle fatigue cycling has been studied. The residual stress distribution and their redistribution upon fatigue cycling were mapped around the FOD notch, using synchrotron X-ray radiation and the contour method. The results suggest that under both impact angles, the FOD event superimposed a significant additional residual stress on top of the pre-existing stress associated with the LSP process. It has been observed that the FOD notch created by 45° impact was asymmetric in shape, and had differential notch depth between the entry and exit side. However, FOD damage that is created at 0° impact appeared as a sharp V notch. A higher amount of residual stresses were produced under 0° impact condition than at 45°. It has been found even though the FOD induced residual stresses relax, residual stresses due to LSP treatment remain highly stable even in the worst condition where a 7 mm long crack was grown from a 45° notch. The plastic zone sizes ahead of a crack tip was estimated for both 0° and 45° FOD impact, and the fatigue crack growth rates are predicted utilizing the measured residual stress distribution.

▼ Aluminum alloys have increasing applications in construction and transportation industries. Both 5xxx-series (Al-Mg) and 6xxx-series (Al-Mg) alloys are frequently used in marine construction because of their light weight, high strength, and corrosion resistance. One of the major concerns regarding the marine application of aluminum alloys is their mechanical performance in fire scenarios. The material strength may be degraded due to both thermal and mechanical damage during fire exposure. This work emphasizes the stress-induced mechanical (physical) damage and its impact on the residual (post-fire) performance of 5083-H116 and 6061-T651 aluminum alloy. Thermo-mechanical tests were performed at various temperatures and stresses to study the stress-induced damage at induced plastic creep strain levels. Unstressed thermally exposed and thermo-mechanically damaged samples were examined to separate the stress-induced microstructural damage. The stress-induced microstructural damage primarily manifests itself as dynamic recovery at low creep temperatures, while cavitation, dynamic recrystallization and dynamic precipitation (in Al6061) are the types of damage developed in the high creep strains at high exposure temperatures. Different creep mechanisms are also studied for both Al5083 and Al6061. The post-fire mechanical response at room temperature after thermo-mechanical damage was investigated with reference to the damaged microstructure present in the material. Residual material strengths based on deformed cross sectional area after the creep test were calculated to provide insight into how microstructural damage affects the post-fire material performance. The competing effects of strength degradation caused by cavitation and strengthening due to grain elongation and subgrain refinement were investigated. Engineering residual material strengths calculated based on the original cross sectional area prior to creep tests were also studied to provide guidance for structural design.

▼ In the MEMS process, a thin film is likely to be coated on a substrate. Residual stress is established in the coating upon cooling to room temperature because thermal expansion coefficients of the thin film and the substrate are different. The residual stress in the coating not only causes bending but also affects the quality of coating. This thesis discusses the relationship of the residual stress and its distribution with the parameters of the process and the thickness of the ITO thin film that is coated on the Si-substrate. Four parameters of coating process - coating time, sputtering power, working pressure, and argon flow rate â are considered here. In the experiment, each parameter is set to one of three levels, consistent with the Taguchi Method, yielding nine combinations. For each of the nine combinations, three Si-substrates are used. Measurements are made at nine points on each Si-substrate. Two sets of the in-plane displacement of the coating from two different angles of the screen can be measured by using digital image correlation technique. The obtained sets of in-plane displacements can be used to calculate the out-of-plane displacement, the components of residual stress in the x-direction and the y-direction can be calculated using the modified Stoneyâs equation. The equivalent residual stress is calculated from these components of residual stresses, and the coefficient of variation is calculated from the average and standard deviation of the equivalent residual stress at the nine points on the Si-substrate. Finally, the distribution of residual stress in coating is discussed with reference to the experimentally obtained coefficient of variation. The experimental results indicate that the coating time and the sputtering power importantly affect the magnitude of residual stress, but the working pressure and the argon flow rate have very little effect. Additionally, the experimental results show that the residual stress distribution is affected by coating time, sputtering power, argon flow rate and working pressure, in order of declining strength of the effect. The coating time most strongly affects the coating process. As the coating thickness increases, the residual stress decreases and the variation among measurements made of three Si-substrates of same combination declines. Restated, the precision of the experimental measurements improves with the coating thickness, but the distribution of residual stress becomes less uniform. Advisors/Committee Members: T. N. Shiau (chair), Jung-Hung Sun (chair), Chung-Ting Wang (chair), Chi-Hui Chien (committee member).

▼ Residual stresses are the stresses which are present within a component without any external load. They can be introduced through any number of manufacturing processes and in-service conditions, meaning that they are almost ubiquitous in engineering components. The characterisation of residual stress is an important field of research particularly in an engineering context since the effects of residual stress sum with the loads. As a result, the performance of a component can be greatly enhanced, or significantly reduced, by the presence of residual stress depending on the sign of the stress and the applied load.In this EngD thesis the focus has been on the development of residual stress through the manufacturing processes of aero-engine forgings, specifically the turbine disc. The forgings studied were sub-scale geometries of the disc, forged from the nickel-base superalloy RR1000. The overall aim of this work is to improve the understanding of the residual stress generation and relaxation through implementation of advanced experimental characterisation techniques, with a view to improving current stress predicting process modelling capabilities. With this in mind the work has focussed on the use of neutron diffraction and the contour method to characterise residual stress experimentally, while residual stress predictions have been made using finite element modelling.The findings of this research indicated that very large residual stresses were generated as a result of the quenching process, and that these stresses were then relaxed and redistributed by ageing heat treatments and material removal by machining. The results obtained through the two experimental techniques exhibited very strong agreement, indicated a robust experimental process. Comparisons to the finite element predictions highlighted some issues with the current model; in particular it was found that the simulation of quenching could be improved by better definition of the heat transfer at the surface. Furthermore, the level of stress relaxation during ageing was consistently over predicted in the model. This result is thought to be the result of an over-prediction of the level primary creep in the alloy. Subsequent studies will investigate this behaviour further using the newly developed in-situ heat treatment capabilities which have developed as part of this research.
