Crystal Plasticity Based Modelling of Surface Roughness and Localized Deformation During Bending in Aluminum Polycrystals
Rossiter, Jonathan (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 ... -
Numerical Modelling of the Effects of High Strain Rate, Strain Path and Particles on the Formability of FCC Polycrystals
Rossiter, Jonathan (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 ...
