Investigation of the effect of crack propagation on weld zone residual stress...

Welds have an associated residual stress field that affects the propagation rate of weld zone defects/cracks. Crack propagation modifies the local stress field through residual...焊缝会伴随产生相关的残余应力场（residual stress field），该应力场会对焊接区域内缺陷与裂纹的扩展速率产生影响。裂纹扩展会通过残余……改变局部应力场。
