Thermoplasticity with diffusion in welding problems
Abstract
A thermomechanical model for the analysis of thermoplasticity with a diffusion term is presented. This model is defined in infinitesimal strain thermoplasticity framework. Thermal hardening is coupled with a diffusion process. The example presents thermodiffusion process in titanium friction welding parts. The migration of hydrogen in the process of thermoplastic deformation is described. Copyright © 2007 John Wiley & Sons, Ltd.
