Characterization and Through Process Modelling of Large Strain Phenomena for Aluminum Alloys at Room and Elevated Temperatures
(University of Waterloo, 2017-02-16)The objective of this research is to model and analyze large strain problems (rolling, hot compression) in FCC polycrystals. In the first part of this research, a rate-dependent crystal plasticity based Element Free Galerkin ... -
Crystal Plasticity based Formability Analysis of Transformation Induced Plasticity Steels
(University of Waterloo, 2018-01-23)This thesis outlines a framework to model to aid the development and utilization of transformation induced plasticity (TRIP) assisted multiphase steels in the automotive industry for light weighting applications. Automakers ... -
Crystal Plasticity Based Modelling of Surface Roughness and Localized Deformation During Bending in Aluminum Polycrystals
(2015-09-25)This research focuses on numerical modeling of formability and instabilities in aluminum with a focus on the bending loading condition. A three-dimensional (3D) finite element analysis based on rate-dependent crystal ... -
Modelling Microstructure-Property Relationships in Polycrystalline Metals using New Fast Fourier Transform-Based Crystal Plasticity Frameworks
(University of Waterloo, 2019-02-04)The present thesis develops several new full-field, fast Fourier transform (FFT)-based crystal plasticity modelling tools for microstructure engineering. These tools are used to explore elasto-viscoplastic deformation, ... -
A New Crystal Plasticity Formulation to Simulate Large-Strain Plasticity of Polycrystalline Metals at Elevated Temperatures
(University of Waterloo, 2017-03-13)This dissertation explores the plasticity polycrystalline metals, with particular attention paid to aluminum and its alloys. Specifically aluminum Al-Mg sheet alloys, which are currently replacing steel parts for panel ... -
A New Crystal Plasticity Model for Steels Exhibiting Transformation Induced Plasticity with Application to Quenched and Partitioned Steel
(University of Waterloo, 2021-05-28)This thesis outlines the development of a constitutive model and the modelling techniques required to accurately model steels that exhibit transformation induced plasticity over a wide range of strain-rates and temperatures. ... -
Numerical Modelling of the Effects of High Strain Rate, Strain Path and Particles on the Formability of FCC Polycrystals
(University of Waterloo, 2010-01-11)A new crystal plasticity scheme for explicit time integration codes is developed based on a forward Euler algorithm in the first part of this paper. The new numerical model is incorporated in the UMAT subroutine for ...
