摘要:
在原有焊接试验基础上，展开任意拉格朗日−欧拉(ALE)法下的螺柱型冲击焊数值模拟研究. 数值模拟研究结果与实际焊接试验结果高度相似，模拟结果可以真实反映实际焊接试验情况. 结合模拟数据，分析试样剖面不同位置的剪应力、压应力及对应的应变分布情况，佐证了应力波是形成波状界面的重要机理.

Abstract:Based on the original welding test, the numerical simulation of stud impact welding with arbitrary Lagrangian-Eulerian (ALE) method was carried out. The numerical simulation results were highly similar to the actual welding test results, so the simulation results could truly reflect the actual welding test. Combined with the simulation datas, the distribution of shear stress, compressive stress and corresponding strain at different positions of the sample section were analyzed, which proves that the stress wave was an important mechanism for the formation of wavy interface.
