Quantitative and consistent tests for interlayer adhesion in laminated glass
… simple strength of materials analyses and the measured load deflection response. The numerical analysis then provided the variation of stress intensity factors, energy release rate and fracture mode-mix with crack length for the extraction of toughness. Further microscopic analysis of the …

Fault diagnosis and prediction in reciprocating air compressors by quantifying operating parameters
… of a reciprocating air compressor. Using only measured load torques and shaft dynamics, pressures, temperatures, flow rates, leakages, and heat transfer conditions are quantified to within 5%. The load torque acting on the rotor of the machine is shown to be a function of the dynamics …

Statnamic Lateral Load Testing and Analysis of a Drilled Shaft in Liquefied Sand
Three progressively larger statnamic lateral load tests were performed on a 2.59 m diameter drilled shaft foundation after the surrounding soil was liquefied using down-hole explosive charges. An attempt to develop p-y curves from strain data along the pile was made. Due to low quality and lack of …

Towards the Development of an Adaptive Rehabilitative Device
… increase support base area, reduce paretic-limb load, and provide somatosensory feedback. However, to improve the quality of life of patients, there is a need to develop a walk-aid that can actively improve the user’s balance. In upper-limb rehabilitation, robot-aided therapy has shown to …

Series expansion of the Modified Einstein Procedure
… by fitting the concentration profile to the measured points. Lastly, SEMEP uses the measured unit sediment discharge and Ro to determine the unit bed discharge directly. Thus, SEMEP can determine the unit bed discharge (qb), unit suspended sediment discharge (qs), unit total sediment …

Long-term Durability Characterization and Prediction of a Urethane-based Adhesive
… the shape of a "T" for gripping in a universal load frame. Unlike some other test geometries, T-peel samples are often made with relatively thin adherends that may experience significant plastic deformation during testing. This extraneous energy dissipation greatly complicates the analysis to …

Numerical Study and Load and Resistance Factor Design (LRFD) Calibration for Reinforced Soil Retaining Walls
Load and resistance factor design (LRFD) (often called limit states design (LSD)) has been mandated in the AASHTO Bridge Design Specifications and will be adopted in future editions of Canadian Highway Bridge Design Code for all transportation-related structures including reinforced soil retaining …

Development of a representative volume element of lithium-ion batteries for thermo-mechanical integrity
… in casings and without casings under multiple loading conditions. These included lateral indentation by a rod, axial compression, through-thickness compression, in-plane unconfined compression, in-plane confined compression, hemispherical punch indentation and three-point bending. Extensive …

Using far-field measurements for determining mixed-mode interactions at interfaces
… of global and local measurements including load-displacement, crack extension, crack tip opening displacement, and fracture resistance curves. Mixed-mode interfacial fracture experiments were conducted using the end loaded split (ELS) configuration for a silicon-epoxy interface, where the …

Ductile fracture after complex loading histories : experimental investigation and constitutive modeling
… from the widely studied proportional loading paths. Different from previous works on the ductile fracture of sheet metal, this thesis research addresses the experimental and modeling issues related to the crack initiation in advanced high strength steels after loading direction …
