▼ Recrystallised alumina is used as a high performance crucible material. Its thermal shock resistance is known to be affected by component shape, and also by processing variables, since the defects and internal stress at both the microscale (i.e. between grains due to anisotropic crystal properties) and macroscale (i.e. due to differential shrinkage during sintering) influence the fracture strength. The aim of this thesis is to study the nucleation and growth of defects in pure alumina and Cr-doped alumina, and to investigate how their behavior is affected by residual stresses, such those introduce by thermal expansion of the crystal grains.In this thesis, digital image correlation is applied to polycrystalline aluminas (i.e. Cr-doped alumina and pure alumina with average grain 3.6 µm and 1.5 µm respectively) that are stressed in an optical microscope. The defect size and the surface crack opening displacement were measured using digital image correlation. The distribution and population of crack nucleating defects were obtained by in-situ observation of the stressed surface and by analysis with digital image correlation. These data are then compared with independent measurements of the defect population using Hertzian indentation, from which defect populations are derived for the pure and Cr-doped alumina samples.Grain boundary plane and grain orientations in the vicinity of crack nuclei were characterised by electron microscopy. Crack nuclei were shown to develop at boundaries predicted to have high tensile thermal strains, caused by the orientation of the grain boundary plane relative to the adjacent grains, such as basal plane grain facets. The techniques of focused ion beam (FIB) milling and electron backscatter diffraction (EBSD) characterization of the crystallographic orientations and structure of cracked grain boundaries were used to provide data for a model to explain the cracking of these boundaries as a result of the thermal strains and the anisotropic thermal expansion behaviour of alumina.

▼ Two-phase Ti6246 alloy is a light weight material exhibiting very high strength at higher temperatures compared to the commonly used Ti64 alloy. This particular alloy is used at the later stages of compressor discs within the aero engines. However, compressor discs undergo a number of cyclic stresses, which could eventually lead to fatigue failure. In order to optimize the microstructure for design and lifing models, an improved understanding of the localised deformation mechanisms is crucial, particularly at the surface, as cracks can be initiated leading to failure and in turn affect the life expectancy of the component. Two-phase alloys in use have very complex lamellar microstructures comprising of a mixture of coarse and fine phases and their role in deformation can be very complex and difficult to understand. The focus of this study was particularly based on the importance of the beta phase in strengthening two-phase microstructures. Therefore, this study has been simplified to compare model lamellar microstructures, which have particular sizes of beta phase in between alpha lamellae. Digital Image Correlation along with high resolution imaging was used to develop a detailed understanding of the localised deformation in these microstructures. Widening the beta phase in-between alpha lamellae caused a more homogenous deformation, while ageing the beta phase with fine secondary alpha strengthened the microstructure. However, all microstructures showed that the single continuous alpha layer at beta grain boundaries depicted the highest amount of deformation, which can be detrimental for the life of the component. The behaviour of slip at the α/β interface not only depended on the size of the phases but also depended on the neighbouring crystallographic orientations and the relationship of the two phases, specifically the alignment of the close packed slip directions. Strain maps of these microstructures were subsequently related to corresponding Schmid factor maps and crystal plasticity models to improve this understanding.

▼ Lymphoedema, particularly as manifested in a secondary form following previous intervention or trauma, is a progressive and debilitating disorder, embodied through the gradual volumetric swelling of a patient’s limb(s), often leading to fibrosis as well as loss of limb function in extreme cases. Compression-based therapy, the most prevalent prophylaxis and post-onset treatment approach for lymphoedema, has shown only limited success. A clear lack of standards, i.e., guidelines insuring consistency of structure and function of lymphoedema compression sleeves, hinders progress toward finding a cure for lymphoedema and prevents testing of sleeve efficacy. The body of work included in this thesis highlights the specific areas of focus necessary to move the field forward and sets a path towards comprehensive profiling of compression sleeves, to understand the underlying mechanisms relevant to efficacious treatment at the interface of the sleeve and skin. Current high-resolution commercial pressure sensors proved ineffective for measurement of spatial and temporal pressure profiles of sleeves in situ; limitations of such compliant sensors, and specific areas of needed improvement, were identified. Promising prototypes of flexible, high-resolution custom sensors were also assessed, with preliminary data and their shortfalls leading to definition of technical specifications for the future. Finally, a Digital Image Correlation (DIC)-based approach was applied to map strains of compression sleeves in high resolution and in situ. The DIC-method platform was tested and validated as a means to provide qualitative and quantitative characterisation of compression sleeves as a function of sleeve size, class, and manufacturer independent of lymphoedema state. Unexpected differences in pressure profiles underscore the need for both standardisation of sleeve design as well as follow on studies testing sleeve function in lymphoedema patients. Looking toward the future, testing of efficacy and head-to-head comparison of standardised and bespoke garments will better enable mechanistic understanding of lymphoedema's aetiology, unraveling how the ‘global’ disease state emerges from ‘local’ events, leading to a basis for lymphoedema prevention in the future.

▼ Rail and bridge infrastructure assets are critical elements of Canada’s transportation network and their continued efficient and safe operation is necessary to ensure the nation’s economic livelihood. Monitoring technologies that can detect changes in performance as well as precursors to failure are an important element of ensuring this efficient and safe operation. Digital Image Correlation (DIC) is a monitoring technology that has the potential to provide critical data for infrastructure assessment and to replace various conventional sensors with one integrated monitoring solution. In this research, the accuracy of DIC is evaluated using numerical, laboratory and field-based experiments. The sources of error of particular relevance to dynamic measurement using DIC are identified as (i) bias error in the sub-pixel interpolation scheme, (ii) the ratio of sample rate to the frequency of the signal being monitoring and (iii) the signal to noise ratio. It is also shown that the chosen sub-pixel interpolation scheme can greatly affect the accuracy of dynamic measurements. The use of DIC was investigated for field monitoring of both horizontal and vertical railway displacements at sites with good and poor subgrade conditions under dynamic train loading. It is shown that there is a significant benefit to using an absolute displacement measurement system rather than a relative displacement measurement system as the former can capture irrecoverable rail displacements in both the vertical and horizontal directions. Finally, DIC was also used for field monitoring of a very stiff reinforced concrete bridge during static and dynamic load tests. It is shown that when using DIC for deflection monitoring, corrections may have to be made to compensate for errors such as camera jitter and drift to acquire the most accurate results. Two potential correction methods were the use of a fixed reference point and generating composite images using average pixel intensity values from multiple images. It was found that using a fixed reference point was the optimal choice in this bridge test. It is concluded that DIC can be used as an effective displacement measurement tool for bridge assessment because it shows excellent correlation with linear potentiometer results and it can allow measurements to be taken without having to close the bridge.

Fascicle shear is theoretically a mechanism by which skeletal muscles lengthen. Existing ultrasound based techniques allow measurement of muscle architecture parameters, but not the quantification of shear strain. In this study, an algorithm that tracks the shear strain from ultrasound images using a continuum representation of the muscle was developed. Errors in strain tracking may arise due to misalignment of the imaging plane, movement artifacts and non-uniform strain within the muscle. The goal of this study was to develop and validate the newly developed strain tracking algorithm. Various potential sources of error are investigated. A computer model was created consisting of a three-dimensional (3D) synthetic volume, representing the muscle. Virtual ultrasound images were then sampled from the 3D volume by intersecting the synthetic volume under a known angle of the imaging plane. The measurement error was defined as the difference between the known strain that was imposed virtually to the 3D muscle volume and the strain calculated with the tracking algorithm. The measurement error was determined for conditions of combined axial and shear strain, plane misalignment, plane rotation and non-uniform strain. Conditions were simulated between 30 and 100 times, each time with a different synthetic muscle volume. The developed strain tracking algorithm provided strain measurement of sub-pixel accuracy and precision when the imaging plane was aligned with the fascicles. Rotation of the ultrasound transducer relative to the muscle resulted in invalid measurements. Axial strain was overestimated when the muscle exhibited a non-uniform axial strain pattern. Largest errors (underestimation of strain by up to 65%) were caused by misalignment of the imaging plane with the fascicles. The large effect of misalignment emphasizes the need for careful transducer placement that requires anatomical information about the muscle structure. Strain tracking methods based on three-dimensional avoid the need for alignment, potentially allowing more accurate measurement of strain.

▼ Digital Image Correlation is a cheap and easy to use measurement method that has been proved to characterise any solid material parameters up to plastic deformation range. The digital image correlation measurement system is based on the tracking of a collective number of pixels from the surface of the reference image to the deformed image. This summation of pixels is called subset. To achieve a reliable measurement in DIC, each of the subsets must contain sufficient speckle pixels. Therefore, there is a firm distinctive intensity pattern contained in a particular subset relative to other subsets. However, with the current DIC method, the user must rely on the intuition and experience for determining these number of speckle pixels. To investigate this problem, a study of measurement and monitoring the behaviour of crossbeam in Orthotropic Bridge due to in-plane quasi-static load is conducted. The reliability of DIC method on measuring strain and deformation in an elastic zone of a steel material is also examined and compared to the other measurement technique such as strain gauge and LVDT. Also, a finite element model is developed to estimate the strain and out-of-plane deformation at the certain location of the crossbeam. The study focuses on the specific location at the crossbeam with ‘haibach’ shape cope hole, where the strain concentration is expected to be significantly high. The applied quasi-static load is set until 250 kN, with strain gauges and LVDT are installed at the same side of the crossbeam (free edge side), and DIC is installed at the exact opposite side (inner side). Parallel with the test on the Orthotropic Deck Bridge specimen, several benchmarking test is also conducted. These tests are used to examine the problems encountered during the initial experiment. The study shows that owing to the quasi-static in-plane load, the crossbeam encounter an out-of-plane behaviour. Therefore, to achieve an accurate measurement, a 3-D DIC measurement system is obliged to use. Strain observed into two different directions: x and y-direction, gives different results in term of accuracy. Due to the low strain limit of DIC system, the result in x-direction can be considered as unreliable. For strain measurement in y-direction, some of the results exceeding the low limit strain of the equipment, give a close match result with the strain gauges, within the acceptable amount of deviation. For out-of-plane deformation, all the measurement show a good agreement between the DIC and LVDT technique. The average speckle pattern size that is used in this research is 0.2 mm, and an average area of 38 pixels2 for a particular speckle pattern. One of the benchmark study shows that under the same condition with same expected level of displacement, an average speckle pattern area between 36 and 45 pixels2 leads to reliable 3D measurement. The finite element model that has been developed in this study also gives close strain estimation for both x and y-direction, compared to the measurement data (DIC and strain gauges).… Advisors/Committee Members: Veljkovic, Milan (mentor), Pavlovic, Marko (mentor), Kolstein, Henk (graduation committee), den Besten, Henk (graduation committee), Delft University of Technology (degree granting institution).

▼ Additive Manufacturing (AM) is a manufacturing process which produces near net-shape components by progressively building them layer by layer. There has been considerable interest in using additive manufacturing of titanium alloys for aerospace, due to advantages such as part cost reduction and increased flexibility in both manufacturing and product design. However, using Ti6Al4V in AM processes can lead to microstructural heterogeneity and, in particular, a coarse columnar beta grain structure, which results in mechanical anisotropy. In this research, the titanium alloy Ti6Al4V walls produced by the Wire Arc-Based Additive Manufacturing (WAAM) process was investigated, which has a high deposition rate suitable for building large-scale aerospace components. In the first part of this study, an as-deposited, single bead wide parallel Ti6Al4V wall built with the WAAM process was characterised with a multi-scale approach using various microscopy techniques, in order to understand and investigate the mechanisms involved that relate to the formation of their heterogeneous microstructure. This work was underpinned by using thermal simulations to study the effect of rapid heating on the transus temperature and to replicate the thermal cycle experienced in HAZ bands. The nature of the finer, weak contrast fusion boundary segregation bands was also examined, and microsegregation of Al, V and Fe was found, with the use of EPMA compositional analysis. The transformed microstructures of the as-deposited (unrolled) samples were then compared with an inter-pass rolled material, which incorporated an additional process step that lightly deformed the deposited material between added layers and results in a recrystallised finer beta grain structure. This resulted in an improvement in the mechanical properties, such as the tensile strength and overall anisotropic behaviour, which was found to be due to the refinement of the alpha-lath microstructure and the formation of a more uniform prior beta grain size and texture randomisation. Suggestions for the overall reduction in alpha lamellar spacing seen during the inter-pass rolling build process were also explored. The effect of the subsequent related transformation microstructure heterogeneity on the mechanical behaviour was investigated, in both standard Ti6Al4V WAAM materials and samples subjected to inter-pass rolling. Full-field strain maps were produced by Digital Image Correlation (DIC), using tensile samples loaded in different orientations. In the unrolled specimens, the results showed that the strain localisation behaviour was highly dependent on the loading orientation. This was then followed by electron backscatter diffraction (EBSD) texture analysis, to explain the effect of local texture on the strain localisation behaviour. Overall, the beta grain refinement, through the application of inter-pass rolling was found to be very effective at homogenising the strain distribution. However, an abnormally rolled condition was found to produced locally coarse grains, which was…

▼ In this work, the wide range of properties of a photodegradable polymer are exploited to generate a host of different inhomogeneous arrangements that can help us experimentally study crack path selection problems. The model material which we are using is a polyethylene co-polymer, ECO, whose photosensitive behavior allows alterations in its mechanical properties when subjected to ultraviolet (UV) irradiation. It is seen that ECO becomes stiffer but more brittle upon UV irradiation. Material degradation in such polymers enables their use as an environmentally friendly material that can be broken into smaller nontoxic parts under small forces such as wind and light. This model material is then used to generate microstructures that possess either discrete or distributed local inhomogeneities similar to granular materials, i.e.,metals. The first part of this literature describes the experimental work done on the three microstructures developed. The microstructures all exhibited the same grain properties but possessed varying grain boundary properties. Each microstructure was loaded in a single edge notch tension (SENT) configuration, and the resulting strain fields were recorded using digital image correlation (DIC). Depending on the applied load and the local microstructure, different crack paths occur, such as the main crack simply extending, or a main crack arresting and a host of secondary cracks appearing at critical locations. Additionally, different types of failure occur within the granular inhomogeneous model displaying intergranular and/or transgranular failure for specific hours of UV irradiation. The DIC results, correlated with global load-displacement measurements, shed light on the conditions under which local crack nucleation and growth can occur. In the second part of this work, the global load-displacement results are compared with a finite element model using ABAQUS. Two different models, interface and interphase, are created to assist in validating the experimental results. Through comparison of the global load-displacement results with the experimental and numerical study, the different developed models can be seen to represent a particular microstructure. A failure criteria is also considered using numerical analysis by analyzing areas of high stress levels using the von Mises and Tresca yield criteria. These criteria illustrate areas in which high magnitudes of stress occur and these results are compared with the experimental failure initiation sites.

▼ A surface instability apparatus (SIA) was used to reproduce spalling in a laboratory setting, and damage in the rock was monitored by acoustic emission (AE) and digital image correlation (DIC) techniques. Lateral displacement served as the feedback signal to control the post-peak response with a closed-loop, servo-hydraulic load frame. Two types of clustering analysis, spatial clustering through the fractal dimension and hierarchical clustering through a dendrogram construction, were performed to analyze AE locations. Results showed an increasing FD as the damage level developed. The fractal dimension was close to 2.0 at lower load ratios, representing a planar distribution of samples. Then FD increased to a value of 2.4 to 2.5 in the post-peak stage, meaning a more scattered distribution in space. The hierarchical clustering was applied to low signal to noise ratio events provided "super AE" locations, a group of events with similar wave signals. These locations matched the crack trajectories. DIC was used to investigate incremental displacement fields during surface spalling. Real-time images were successfully captured under high stress levels through modification of the device. Displacement fields computed by DIC were through the comparison of two digital sub-images (subsets) with a unique white-light speckle pattern, and strain fields can be estimated from the displacement information. A continuum damage mechanics model was used to describe the damage progression in surface instability test. The continuity parameter serves as a state variable representing the evolution of damage, which is linked to the inelastic total lateral strain computed from the displacement fields using DIC. The critical value of inelastic total lateral strain was selected at the moment of spalling being captured by the digital imaging system. For the two Berea sandstone and one Serena sandstone specimens, consistent values were observed. This observation implies that the critical inelastic lateral strain may provide an indicative metric for determining the moment of surface instability.

▼ In the structural engineering community, a need exists for a non-contact two-dimensional measurement system which could provide information for field monitoring and greatly enhance the accuracy of numerical structural models. Recent advances have enabled the use of digital image correlation (DIC) to calculate the surface displacements of chosen targets in a series of digital images with a high degree of accuracy. Images are recorded during an experiment and are afterwards post-processed to find relevant information including, but not limited to, a) global displacement, b) relative displacement and c) changes in strain. In this research, a series of experiments were conducted to create measurement techniques for monitoring steel and reinforced concrete (RC) structures utilizing DIC. However, to ensure accurate DIC measurements, the addition of artificial texture from lightly applied spray paint on finished concrete was investigated and was determined to noticeably improve results. Furthermore, the placement of the digital camera relative to the structure being monitored was shown to control not only the desired field of view in the region of interest, but also the resulting image texture and DIC measurement accuracy. The DIC technique was applied to monitor and understand two important aspects of structural evaluation: a) the movement along shear planes and b) the evaluation of changes in strain due to curvature in beam elements. To monitor the change in crack width and slip, a method was created and validated on a series of artificial and reinforced concrete images for the cases of pure shear, pure flexure and combine flexure and shear. Curvature was found to impact the crack slip measurement, but its effect can be removed by using an innovative averaging technique. The curvature of a steel HSS and RC beams was found by using virtual DIC strain gauges and the horizontal strain profile. Results matched well with the curvature from electrical foil gauges and numerical models when the gauge length was maximized and selected so that the effects of cracking were accounted for.

▼ Finite element models are used frequently in both engineering and scientific research. While they can provide useful information as to the performance of materials, as length scales are decreased more sophisticated model descriptions are required. It is also important to develop methods by which existing models may be verified against experimental findings. The present study evaluates the ability of various finite element models to predict materials behaviour at length scales ranging from several microns to tens of nanometers. Considering this motivation, this thesis is provided in manuscript form with the bulk of material coming from two case studies. Following an overview of relevant literature in Chapter 2, Chapter 3 considers the nucleation of delta-zirconium hydrides in a Zircaloy-2 matrix. Zirconium hydrides are an important topic in the nuclear industry as they form a brittle phase which leads to delayed hydride cracking during reactor start-up and shut-down. Several FE models are used to compare present results with literature findings and illustrate the weaknesses of standard FE approaches. It is shown that standard continuum techniques do not sufficiently capture the interfacial effects of an inclusion-matrix system. By using nano-scale material descriptions, nucleation lattice strains are obtained which are in good agreement with previous experimental studies. The motivation for Chapter 4 stems from a recognized need to develop a method for modeling corrosion behaviour of materials. Corrosion is also an issue for reactor design and an ability to predict failure points is needed. Finite element models could be used for this purpose, provided model accuracy is verified first. In Chapter 4 a technique is developed which facilitates the extraction of sub-micron resolution strain data from correlation images obtained during in-situ tensile deformation. By comparing image correlation results with a crystal plasticity finite element code it is found that good agreement between the two exists. The method outlined is material independent and could be applied to most metallurgical studies. Chapter 5 reviews the findings of each case study and makes suggestions as to the direction of future research.

▼ Bulk metallic glasses often exhibit exceptional strength and large elastic strains, but the structural applications of bulk metallic glasses are limited by their extremely low tensile ductility. Below the glass transition temperature of the alloy, plastic deformation occurs primarily in narrow shear bands, which propagate unimpeded through the monolithic glass structure, resulting in catastrophic failure under tensile loading. A number of studies have added crystalline reinforcements to the glassy matrix in an effort to block shear band propagation and increase ductility. The reinforcements in these bulk metallic glass matrix composites (BMGMC’s) can be added as ex situ particles or fibers infiltrated by the glass- forming liquid, or can be formed in situ, either via devitrification of the glass during post-processing or as a second phase that precipitates from the melt during solidification . The size, distribution, and mechanical properties of the reinforcement phase have significant impact on the ductility of the composite. However, surprisingly little quantitative microstructural information is available for BMGMC’s, particularly those formed by precipitation from the melt.In this work, we examine two in situ BMGMC’s in which a ductile crystalline phase precipitates during solidification of the melt, resulting in a complex dendritic structure embedded in a continuous glass matrix. A 3D serial sectioning process was used to image the microstructure at regular intervals by removing slices of material using a dual beam focused ion – scanning electron microscope (FIB). Due to the complex nature of the microstructure, measurements of key features were conducted using a 3D measurement method that was developed for this purpose. Experiments were also conducted to provide experimental input for the development and tuning of finite element models. Changes in the elastic modulus of the composite were evaluated over a range of stresses that encompassed the yield point of the composite. An interesting increase in the modulus was observed prior to yielding. The work is concluded with a study of the accumulation of strain within the composite microstructure during tensile loading. The strain was determined and evaluated by a digital image correlation method. Advisors/Committee Members: Flores, Katharine (Advisor), Windl, Wolfgan (Advisor).

Widespread use of metal plate connections to connect wood-truss-joints (in industrial buildings, residential and housing, and commercial buildings) opened the doors to create opportunities for more research in studying the behavior of MPC's. Thus, the need for an accurate understanding of the performance and properties of the metal plate connectors and the wood members has risen to get an efficient and accurate analysis and design of MPC which could mean major savings in time and money. None of the previous research in metal plate connections contained measurements of the entire surface displacements or strain (local) of the metal plate connections. The measurement of strain (displacements) plays an important role in experimental stress analysis and in the evaluation of material properties. Several experimental methods and devices are used to measure displacements: Moir� techniques, laser speckle, Strain gauges etc. However, digital image correlation (DIC) has been successfully applied to measure the full-field strain and displacements.Digital image correlation (DIC) technique is a well-established approach that is used to find the full-field strain (local) measurements for MP connected joint surface.The MPC were studied in four-tensile joint configuration and heel joint. 2D-DIC code is used to find the full-field strain measurements. The results from the DIC are used to find the yielding stress for the first test AA under tensile force. The heel joint full-field strain measurements show the changes in the strain under loading and the influence of the rotation of the top chord wood member.
