Other Abstract

A new multi-physics coupling numerical model for friction stir welding was established based on coupled Eulerian-Lagrangian (CEL) method. The model was utilized to simulate the material flow and defect formation in the weld during welding. The friction stir welding was conducted to verify the model through the comparison of temperature field, macro morphology of weld, plastic strain in the weld and welding defect. The results show that the simulation temperatures agree well with the measured data and the maximum error is 23.4 ℃. The macro morphology of the weld, the plastic strain zone shape and size on the weld cross-section are in good agreement with the actual weld. The model can accurately predict the formation of void defect in the weld, and the simulated void position is consistent with the actual position. But the void size is overestimated slightly.
