摘要：

With ALE (Arbitrary Lagrangian-Eulerian) mesh adaptive technique and proper management of corresponding boundary conditions, thermo-mechanical coupled finite element model of whole process of friction stir welding (including under pressure stage and stable welding stages) was established. The model was tested by a 6061 aluminum alloy weldment. The results show that the highest temperature of the whole process temperature field is about 463℃, under its melting point. At 6s of stable welding stage, the plastic deformation field distribution on the cross section behind the tool looks like a V shape, the degree of deformation and the deformation region at the advancing side is more intensely and larger than that at the retreating side. ©, 2014, Beijing Institute of Aeronautical Materials (BIAM).
