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 ... -
Monotonic and Fatigue Performance of RC Beams Strengthened with Externally Post-Tensioned CFRP Tendons
(University of Waterloo, 2007-05-04)External post-tensioning is an attractive technique for strengthening reinforced concrete structures because of its ability to actively control stresses and deflections, speed of installation, minimum interruption for the ... -
Partial Joint Penetration Welds in Aluminum Structures
(University of Waterloo, 2020-09-29)Aluminum structures are becoming more and more common in Canada and the world as engineers and decision-makers become more aware of the possibility to lower life cycle costs. Aluminum's corrosion resistance, light weight ... -
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 ... -
Resistance Spot Weld Fatigue Life Prediction Method Compatibility with Self-Piercing Rivets
(University of Waterloo, 2022-06-15)The Resistance Spot Weld (RSW) is traditional method for structural sheet metal joining with well established durability assessment techniques and methodologies. With increased prevalence of multi-material automotive ... -
Understanding the effect of objective function weightings on posture prediction: application to predicting lifting postures in un-fatigued and fatigued states
(University of Waterloo, 2021-04-28)Physical prototyping is often required when developing new equipment and workspaces so that human-systems integration can be considered. Digital human modelling facilitates more efficient, upstream assessment of human ...
