A Study on the Strain-Rate- and Stress-State-Dependent Behavior of Advanced Ceramics: Experimental Mechanics and Multiscale Simulations
DownloadFall 2024
Design and development of better-performing ceramic structures are vital in industry-driven applications where a wide range of strain rates and stress states are induced in the material (e.g., impact events). Accordingly, this thesis investigates the strain-rate and stress-state-dependent...

Development of Microstructure-Informed Computational Models for the Design of Cold-Sprayed Additively Manufactured Metal-Ceramic Composite Materials
DownloadFall 2024
This thesis develops microstructure-based finite element (FE) models of cold-sprayed additively manufactured (CSAM) metal-ceramic composites – Al-Al2O3 in this research – to fill a gap in our understanding of the microscale failure progression in the material in correlation with its macroscale...

Assessment of Bio-jet Fuel Production through Alcohol-to-Jet Pathways from Lignocellulosic Biomass
DownloadFall 2024
The aviation industry worldwide consumes approximately 1.531.7 billion barrels/year ofconventional jet and 140 million litres/year of bio-jet fuel and it has been estimated thatcommercial aviation has contributed approximately 2-6% to global carbon emissions. Biomassderivedjet (bio-jet) fuel may...

A Laboratory Study on the Kinematic and Pressure Responses of an Internally Pressurized Novel Surrogate Headform Subjected to Blunt Impacts
DownloadFall 2024
Instrumented surrogate head models – each of which exhibits varying degrees of complexity – are employed to study traumatic brain injury and mild traumatic brain injury. Despite advancements over the years, many existing surrogate head models lack a pressurized cerebrospinal fluid (CSF) or...

Experimental Studies and Multi-Scale Modelling of Advanced Ceramics: Fracture, Fragmentation, and Failure
DownloadFall 2024
The objectives of this thesis is to explores the mechanical behaviour of alumina ceramics, focusing on fracture and fragmentation response through a blend of experimental investigations and advanced computational modelling. To bridge the gap between micro-mechanisms and macroscopic material...

Fall 2024
Hydrodynamics of the flow around multi-foil systems, representing the tailfin dynamics of collectively swimming fish or fish schooling, were investigated by directly solving the Navier-Stokes equations across a range of flow conditions. The wake and performance of the pitching foils in schooling...

In 2021, the City of Edmonton (CoE) released an Energy Transition Strategy and Action Plan (ETSAP) outlining how Edmonton can achieve ``net zero" greenhouse gas (GHG) emissions by 2050. The plan indicated that 83\% of GHG emissions could be reduced between 2020 and 2050 through energy savings and...

Development and Experimental Validation of an Impactor for Osseointegrated Transfemoral Implant Stability Assessment
DownloadFall 2024
Osseointegrated transfemoral implants are a promising alternative for individuals who are unable to use a socket prosthesis; it is generally accepted that bone-anchored prostheses can improve patient quality of life. Osseointegration is the long-term process of implant anchorage in bone, caused...
