Numerical Simulation of Aluminum Alloy Welding for Butt-Joint of AA2024 Considering Surface Effect Element

Abstract:

Aluminum has higher conductivity, convection coefficient, and oxidability, which casuse low plasticity in high temperature compared to convectional low carbon steel. These properties make its welding numerical simulation much more difficult. Thermal simulation is the foundation of aluminums coupled calculations of thermo-elasto-plastic for welding. In this paper, a butt-joint of aluminum AA2024-T3s welding is numerical modeled based on surface effect element. And bilinear kinematic hardening is used to take into the Bauschinger effect. The simulation results agree well, which shows that node temperature calculation can be improved by this method.
