Abstract:
The main point of successful manufacture of metallic composites by direct bonding of dissimilar materials is achieving a homogeneous interface bonding. Two different types of deformation techniques for fabrication of metal composites were investigated. The first one was developed on the basis of high pressure torsion associated with a high energy impact on the material where part of energy involved can be dissipated via non equilibrium phase transition realization. This deformation due to high shear deformations allows not only to form a nanostructure, but also to bond dissimilar metals. Moreover, this method allows for a relatively short time and in a number of compounds to receive in one step at room temperature monolithic composites of sufficient size to certify the structure and properties. The second technique is diffusion bonding which integrate one material with the other by pressure under high temperature. In order to clarify the bonding mechanism by plastic deformation of dissimilar materials, the microstructural and some mechanical properties were studied in the processed samples.

Abstract:
The necessity of establishing and determining the consistency of mortars deformation in the horizontal joints of masonry is established: in the absence and development of cracks and with the exhaustion of resistance ranging from 80 – 85 % of the total deformation of masonry under short-term compression. Attention is paid to the absence of reports in the scientific literature on the conduct and results of research on the spatial stress-deformative state of the mortar in the joints of masonry under compression. The advantages of studying the secant modulus of deformation Ep are emphasized in solving various issues in the theory of operation and method for calculating the masonry. On the basis of long-term research results, the essential difference between the change in the secant modulus of cement mortars deformation E'p of varying strength of horizontal joints from the nature of its change when tested in standard samples is shown analytically and graphically. The advantages of the developed methodology for processing the results of investigations of mortars in standard samples are noted. It allows to more accurately set the actual values of normal strain modulus E0 and the ultimate relative deformation under compression. The analytical dependences of the plasticity coefficient and the secant modulus of deformations E'p are found based on processing the results of numerous studies of masonry mortars

Abstract:
Severe plastic deformation (SPD) is used to convert traditional coarse grain metals and alloys into ultrafine-grained (UFG) materials. UFG materials possess a number of improved mechanical and physical properties which destine them for a wide commercial use. However, any attempt to use SPD technology commercially requires a better insight into the mechanics and practicality of SPD processes. This paper looks into historical development of SPD processes and focuses on such aspects of SPD as material flow, role of hydrostatic pressure, friction, geometry of tools, billet and feeding considerations, technical feasibility, etc. The discussion of these topics sets a background for decisions concerning further research and commercialisation of SPD.

Abstract:
Zirconium diboride, ZrB2, based materials have been proposed for structural applications at ultra-high temperatures (>2000 [degrees] C). However, their mechanical behaviour at such temperatures is only poorly documented. In this work, the processing and the deformation behaviour of ZrB2 at temperatures up to 2000 [degrees] C is investigated. Densification of zirconium diboride based materials is difficult and most reported routes use a combination of high pressures and high temperatures to obtain a high density. However, it had been reported that with the aid of carbon, boron carbide and silicon carbide, pressureless sintering of ZrB2 is possible. Further work in this thesis shows that the key factor to obtain successful sintering is to limit the oxidation of the raw materials. It is shown also that dense materials can be obtained from relatively coarse powders with only carbon as the sintering additive. Adding silicon carbide or boron carbide does allow the grain growth at the sintering temperature to be limited. Mechanical characterisation of these materials was performed firstly using small-scale hardness measurements by nano-indentation at moderate temperatures (25-300 [degrees] C). The indentations were carried out at strain rates in the range 10-4 and 10-1 s-1. An analysis to extract the Peierls stress (6.6 ± 0.7 GPa) and activation energy (2.56 ± 1:6 x 10-19 J) for lattice resistance controlled plastic flow is presented. Additional mechanical characterisation consisted in measuring the self-contact hardness at temperatures from 900-2000 [degrees] C. These measurements clarify that the initial rapid decrease in hardness at room temperature is followed by a region of more or less constant hardness before further decreases in hardness become apparent at the highest temperatures. A TEM investigation of the deformation mechanisms shows that near room temperature, extensive dislocation flow occurs underneath indentations, whereas at the highest temperatures measured in this work, dislocations either anneal out or do not partake in the deformation. The available data was then summarised through proposing a deformation mechanism map for ZrB2.

Abstract:
This thesis presents a systematic study on evolutions of microstructure, microhardness and superplasticity of a Pb-62% Sn alloy processed by both equal-channel angler pressing (ECAP) and high-pressure torsion (HPT) and the subsequent self-annealing process at room temperature (RT). The Pb-Sn alloy exhibits characteristics with significant grain refinement after processing by ECAP and HPT but with a reduction in the hardness values by comparison with the initial as-cast condition. For HPT processing, it is shown that there are generally smaller grains at the edges of the discs by comparison with the disc centres. The hardness results are different from those generally reported for conventional single-phase materials where a hardening trend was commonly observed after HPT processing. The significance of this difference is examined. The microstructures of the alloy after HPT were repeatedly investigated during the course of self-annealing by scanning electron microscopy (SEM), electron backscatter diffraction (EBSD) and scanning electron microscopy (TEM). A significant grain growth combined with increase of microhardness was observed. It was demonstrated that there was a large fraction of twin boundaries with a twin relationship of 62.8°<100> in the microstructure for the as-cast condition. Owing to the presence of high pressure, the mobility of Ʃ21 boundaries at 71° was greatly favoured during processing by HPT. But the mobility of the dislocation-twin boundary near 62.8°<100> was favoured during self-annealing at RT once the high pressure was removed. The HPT processing significantly increased the solubility of Sn in Pb phase. This supersaturated state of Sn in Pb is, however, not stable at RT during self-annealing and therefore a decomposition of Sn from Pb-rich phase was observed after 16 days of storage. Lattice diffusion should be considerable as the main mechanism for the decomposition. Moreover, abnormal grain growth was observed to be greatly favoured during self-annealing when the introduced strain was relatively low, i.e. 2 passes by ECAP and the centre region of a HPT-processed disc after one turn. Consequently, a series of HPT-processed samples with different storage time was tested in tension at RT and at 1.0 × 10-4 - 1.0 × 10-1 s-1. The results demonstrated that, despite the storage time, all processed alloy exhibited excellent RT superplasticity at 1.0 × 10-4 s-1 and the highest elongation of 630% was recorded in the processed alloy after storage for 4 days at RT. The detailed investigation showed, due to the high strain rate sensitivity of the processed alloy, a transition strain rate of ~1.0 × 10-2 s-1 was observed in which stain softening with ductile behaviour is apparent due to active GBS below the transition point but high strength is observed because of grain boundary strengthening above the transition during plastic deformation at RT in the Pb-Sn alloy after HPT. Nanoindentation tests were then performed applying both indentation depth-time (h-t) relationship at holding stage and the hardness, H, at various loading rates to explore the evolution of strain rate sensitivity (SRS), m. The results obtained by both tensile test and nanoindentation show that the relatively fast self-annealing of the HPT-processed Pb-62% Sn eutectic alloy is occupying by an unambiguous changing-tendency of strain rate sensitivity. The results confirm the validity of using nanoindentation for measuring strain rate sensitivity.

Abstract:
<p>A digital image processing system was used to non-destructively measure the full-field deformation on aluminum and wood specimens loaded in compression and bending. The measurement technique consisted of creating a random speckle pattern on the specimen surface, recording images before deformation and after deformation, and computing the relative displacements of small image subsets. Two methods for producing speckle patterns on the specimens were studied: spray paint and adhesive-backed photographic film.</p> <p>Baseline tests were conducted to evaluate the influence of signal noise on the measurement system. Uniform translation tests were conducted to evaluate the capability of the system for measuring finite motion. the technique was used to monitor the full-field deformation response of aluminum and wood specimens tested in bending and static compression. Moderate duration compression creep tests were conducted, on the wood specimens to investigate the suitability of the system for monitoring the creep response of materials. The results obtained from the two speckle techniques were also. compared. The results showed that for the magnification and speckle patterns tested displacement measurements smaller than 3.29x10-4 inch may be unreliable due to signal noise.</p><br>Master of Science

Abstract:
Recent advances in visual sensing technology have gained much attention in the field of bridge inspection and management. Coupled with advanced robotic systems, state-of-the-art visual sensors can be used to obtain accurate documentation of bridges without the need for any special equipment or traffic closure. The captured visual sensor data can be post-processed to gather meaningful information for the bridge structures and hence to support bridge inspection and management. However, state-of-the-practice data postprocessing approaches require substantial manual operations, which can be time-consuming and expensive. The main objective of this study is to develop methods and algorithms to automate the post-processing of the visual sensor data towards the extraction of three main categories of information: 1) object information such as object identity, shapes, and spatial relationships - a novel heuristic-based method is proposed to automate the detection and recognition of main structural elements of steel girder bridges in both terrestrial and unmanned aerial vehicle (UAV)-based laser scanning data. Domain knowledge on the geometric and topological constraints of the structural elements is modeled and utilized as heuristics to guide the search as well as to reject erroneous detection results. 2) structural damage information, such as damage locations and quantities - to support the assessment of damage associated with small deformations, an advanced crack assessment method is proposed to enable automated detection and quantification of concrete cracks in critical structural elements based on UAV-based visual sensor data. In terms of damage associated with large deformations, based on the surface normal-based method proposed in Guldur et al. (2014), a new algorithm is developed to enhance the robustness of damage assessment for structural elements with curved surfaces. 3) three-dimensional volumetric models - the object information extracted from the laser scanning data is exploited to create a complete geometric representation for each structural element. In addition, mesh generation algorithms are developed to automatically convert the geometric representations into conformal all-hexahedron finite element meshes, which can be finally assembled to create a finite element model of the entire bridge. To validate the effectiveness of the developed methods and algorithms, several field data collections have been conducted to collect both the visual sensor data and the physical measurements from experimental specimens and in-service bridges. The data were collected using both terrestrial laser scanners combined with images, and laser scanners and cameras mounted to unmanned aerial vehicles.
