This dissertation is an attempt at the quality analysis of constitutive modelling of welding as a coupled thermo-mechanical or thermo-mechanical-metallurgical problem. Three types of inelastic theories of continua: unified viscoplasticity based on dislocation density theory, unified viscoplasticity based on potential theory, and transformation induced plasticity have been chosen for quantitative investigation. Material models proposed by Anand, Estrin and Mecking, Estrin, Robinson, and Leblond et.al. have been implemented into the finite element program ABAQUS. Specific subroutines have been written specifically for each constitutive equation. The material model implementation is based on the implicit solution of stress-strain relations and the derivation of associated constitutive tangent moduli necessary for the Nonlinear Finite Element solution procedures. Material model comparisons are based on numerical results obtained for the welding of thick plates; that is the bench mark problem considered in this thesis. 2016-03-04T16:34:21Z 2016-03-04T16:34:21Z 1994 Master Thesis Masters MSc http://hdl.handle.net/11427/17443 eng application/pdf Department of Mathematics and Applied Mathematics Faculty of Science University of Cape Town |
