  • 摘要:This work deals with the simulation of fusion welding by the Finite Element Method. The implemented models include moving heat sources, temperature dependence of thermo-physical properties, elasto-plasticity, non-steady state heat transfer, and mechanical analysis. It is assumed that the thermal problem is not coupled with the mechanical one, being the thermal analysis performed separately and prior to the mechanical analysis. The mechanical problem is based on thermal history. A special treatment is performed on mechanical elements during the liquid/solid and solid/liquid phase changes. The three-dimensional stress state of a butt-welded joint is obtained as an example of application..
