Finite Element Analysis of Multi-Material Die-Cast Tooling by Additive Manufacturing
(University of Waterloo, 2024-05-10)The predominant challenge encountered in the high-pressure die casting of aluminum is the deterioration of casting dies because of thermal fatigue or heat checking. This issue largely stems from the inadequate thermal ... -
Finite Element Methods to Analyze Helical Stent Expansion
(University of Waterloo, 2014-07-18)Stent angioplasty or stenting is the standard noninvasive therapy method to address narrowing of the arteries and restore blood flow. Although drug-eluting stents have resolved immediate restenosis (i.e., re-narrowing of ... -
Finite Strain Elastoplasticity: Consistent Eulerian and Lagrangian Approaches
(University of Waterloo, 2009-05-08)Infinitesimal strain approximation and its additive decomposition into elastic and plastic parts used in phenomenological plasticity models are incapable of predicting the hardening behavior of materials for large strain ... -
Fire and Heat Transfer Modelling of Small and Large Scale Experiments
(University of Waterloo, 2020-09-18)The present work aims to provide insight on the small- and full-scale models of building construction materials and structures in fire scenarios. Steps are taken toward a long-term goal, which is to develop a complete model ... -
