Multi-Material and Multi-Joint Topology Optimization of 3D Structures
In recent years, topology optimization has become a popular tool in automotive, aerospace and defense industries to generate novel clean slate designs. The most modern of these tools is multi-material topology optimization ... -
Characterization of Strain Rate Sensitivity, Plastic Anisotropy, and Dislocation Content in Zircaloy-2
Zirconium alloys are used broadly throughout the nuclear industry due to a combination of its mechanical properties, low neutron absorption cross section, and resistance to corrosion. Understanding the process of plastic ... -
Mode I Fracture Testing on Zirconium Foils Under Plane-stress Condition
Zirconium alloys are commonly used in nuclear reactor in-core components due to their good mechanical properties and low neutron-absorption cross-section. Especially for CANada Deuterium Uranium (CANDU) reactors, zirconium ... -
Optical Visualization of Two Phase Flow in PEM Electrolyzers
Polymer electrolyte membrane (PEM) electrolyzers are ideally suited to pairing with renewable energy sources given the capability to operate at high current densities and transition between different potential loading. ... -
Design of Uniformly Textured Polymer Surfaces for Hard-soft Bearing Systems
The aim of this study is to investigate the effect of surface texturing for improving the tribological performance of metal-ultra high molecular weight polyethylene (UHMWPE) bearing systems during intermittent stop-dwell-start ... -
Finite Element Analysis of Cortical Shell Contributions to Apparent Stiffness and the Effect of Vascular Apertures in Rat Vertebrae Under Uniaxial Compression
Osteoporosis is a degenerative bone disease that causes an increase of fracture risk. The present method of diagnosing the disease is through a bone mineral density (BMD) scan which neglects bone quality. Due to the ... -
3-D Design for Additive Manufacturing Utilizing Topology Optimization
As the frontier of modern-day engineering challenges pushes forward, the integration of multiple strategies to reduce manufacturing cost and increase component performance has engineers turning to tools such as topology ... -
Deformation-Induced Phase Transformation in a Quaternary Zirconium Alloy
Zirconium alloys are used extensively in the nuclear industry, largely due to the very low neutron capture cross-section of zirconium. Alloying of zirconium with substitutional solutes, like Sn, Mo or Nb, is common to ... -
Characterization and modeling of near-field BLEVE overpressure and ground loading hazards
Boiling Liquid Exploding Vapor Explosion (BLEVE) is one of the most feared accident in the industry. Even though it has been studied for over 6 decades, many safety questions remain poorly answered: what happens if a BLEVE ... -
Multi-material topology optimization for lightweight design
Multi-material topology optimization remains an active research topic. This work enriches the key techniques of multi-material topology optimization, such as the multi-material property determination, topology optimization ... -
Effects of Microstructure and Particle Population on Void Damage Evolution in Complex Phase Steel
This thesis aims to provide a detailed description of the microstructure and void damage evolution in a grade of hot-rolled complex phase (CP) sheet steel produced by ArcelorMittal Dofasco (AMD). The evolution of ... -
Modelling and Transient Simulation of Solar-powered Hydrogen Energy Storage Systems
Practical energy storage systems are essential for matching the intermittent production of renewable power sources with the time dependent power demand of residences and businesses. This study assesses the technical viability ... -
Methods for Improving Ability to Investigate the Effectiveness of Non-Invasive Treatment Strategies for Medial Knee OA
Osteoarthritis (OA) is the most common form of arthritis, occurring frequently in the medial compartment of the knee. As the onset and progression of medial knee OA has been associated with abnormal and excessive loading ... -
Development of an evaluation framework for eye gaze assistive technology
Children with complex care needs sometimes have difficulty communicating with their parents, caregivers and teachers. For these children eye gaze assistive technology can be used to facilitate communication. The objective ... -
The relationship between knee joint shape and function: Implications for pathology and treatment
Many patient characteristics can affect joint function; yet the implications of this for musculoskeletal disorders and their treatment are not well understood. A better understanding of these relationships could aid in ... -
Numerical Investigation of Mixing Tabs in Multi-Ring Entraining Diffuser in Air-Air Ejectors
This research studied the effect of mixing tabs used in entraining diffusers in subsonic short air-air ejectors. Although numerous studies exist on mixing tabs in nozzles, none was found that placed tabs in an entraining ... -
Exploring Students' Internal Motivation for Engineering Creativity: Creative Confidence and the Arts
This study used a mixed methods approach to investigate undergraduate engineering students’ internal motivation for engineering creativity and student attitude and understanding of creativity in engineering and the arts. ... -
Atomistic simulations of irradiation-induced dislocation loops in zirconium alloys
Irradiation-induced dislocation loops are important defects that affect zirconium alloys used in the manufacture of major structural components of nuclear reactors. In this thesis atomistic simulations and theoretical ... -
Microstructural Evolution and Hardening of Zr-2.5Nb-0.5Cu Spacer Material under Irradiation
Zr-2.5Nb-0.5Cu alloy is considered as a potential replacement of the current Inconel X-750 alloy for future spacer installations in CANDU® reactors. They are designed to be placed in the annular space between pressure and ... -
Towards Carbon Free Energy Systems in Canada: Case Studies in the Ontario Transportation and Canadian Energy Export Sectors
With climate change being arguably the most important problem of this century, solutions must be researched, developed and implemented across the globe. Canada has shown progress over time in the electricity sector to ...
