Abstract
The 3D transient thermal elastoplastic finite element analysis for a butt joint GMAW has been performed. A plastic hardening recovery model has been introduced and examined to consider the solid-liquid and solid-solid phase changes. The effects of cut-off temperatures and plastic hardening models are also examined. The results of numerical analysis show good agreement with those of experiments in both temperature and residual stress fields. The present model shows remarkable improvement in computing time.
