结果表明，在表面焊道下面并且离开焊缝中心线若干距离的地方，出现相当高的三向拉伸应力和大的塑性应变积累。
The results show that the triaxial residual stresses and plastic strains can accumulate to relatively high values just below the surface and at a short distance away from the weld area.
本文讨论了用焊道表面的温度信息对多个模型参数进行在线修正，提高计算模型的适应性。
The method that on-line identifies parameters of the model through the information of temperature on the welding bead surface and thus increases adaptability of model was discussed in the paper.
