Characterization and Modeling of Forged ZK60 Mg Alloys under Quasi-static and Fatigue Loadings
(University of Waterloo, 2020-01-24)In response to impending changes to the environmental regulations on the vehicles’ gas consumption rate, the transportation sector is motivated toward the widespread adoption of lightweight materials in the manufacturing ... -
Design of Ultrasonic Processing Device for Aluminum Surfaces
(University of Waterloo, 2018-01-19)The work in this thesis examines the design possibility of a device capable of harnessing ultrasonic oscillations through resonance such that it can be applied onto an aluminum surface to produce a compressive residual ... -
Development of Computational Multiaxial Fatigue Modelling For Notched Components
(University of Waterloo, 2012-05-03)Fatigue failures of driveline and suspensions components for ground vehicles under multiaxial loading conditions are common, since most those components are subjected to complex multiaxial loadings in service. In addition ... -
The Effects of Elevated Temperature and Laminating on the Quasi-Static and Fatigue Properties of Electrical Steel
(University of Waterloo, 2023-05-24)Electrical steel is an alloy of steel that can have on average 3% silicon. These alloys are known to possess great magnetic properties, and this makes them an ideal material choice for the application of electric motors ... -
Experimental and numerical investigation of split sleeve cold expansion of AZ31B magnesium alloy

Fatigue Characterization and Cyclic Plasticity Modeling of Magnesium Spot-Welds
(University of Waterloo, 2013-07-18)The automotive industry is adopting lightweight materials to improve emissions and fuel economy. Magnesium (Mg) alloys are the lightest of engineering metals, but work is required to assess their structural strength, ... -
Fatigue of Forged AZ80 Magnesium Alloy
(University of Waterloo, 2019-09-25)The majority of research surrounding the fatigue of Mg alloys generally exhibits a rigid dichotomy between theoretical and applied contributions. This research work addresses both of these domains of the field from a more ... -
Fiber Laser Welding of Advanced High Strength Steels
(University of Waterloo, 2013-08-01)Fiber laser welding (FLW) was used to join advanced high strength steel (AHSS) and high strength steel (HSS); specifically two dual-phase (DP) steels, with ultimate tensile strengths above 980 MPa and with different ... -
Influence of drilling and abrasive water jet induced damage on the performance of carbon fabric/epoxy plates with holes
(Elsevier, 2017-03-01)The influence of conventional drilling (CD) and abrasive water jet (AWJ) cutting on the fatigue performance of carbon fabric/epoxy plates was investigated. Observations of machined hole regions revealed more severe damage ... -
Mean Stress Effect in Stress-Life for Hard Steels
(University of Waterloo, 2017-06-01)The work in this thesis examines the effect of mean stress on the fatigue behaviour of very hard (Rockwell C 60) steels (AISI 8822, 8620, 9310, and cold-worked pre-stressing wire). In the mean stress tests, the minimum ... -
Modeling the Residual Stress Distribution and Experimental Characterization of Shot Peening on AZ31B Rolled Sheet
(University of Waterloo, 2020-01-17)The drive to reduce fossil fuel consumption due to its environmental impacts has generated renewed interest in employing magnesium (Mg), the lightest industrial metal, and its alloys in vehicle manufacturing. One of the ... -
Quasi-Static, Cyclic, and Fracture Characteristics of Plasma Transferred Wire Arc (PTWA) Thermal Sprayed AlSi Cylinder Bores
(University of Waterloo, 2022-05-12)This study examines the microstructure and mechanical properties of plasma transferred wire arc (PTWA) coating of typical alloyed steel, deposited on diecast aluminum alloy cylinder bores. The coating surface and microstructure ... -
