Plastic deformation takes place first at the crack tip and spreads across the solid as the applied load is increased beyond generalyielding.
塑性变形首先发现在裂纹顶端，当工作载荷超过了普通屈服时，则传播到物体中。

The surface cracks in welded structures are assessed and investigated directly by the wide plate test according to the generalyielding criteria and COD parameter.
本文通过宽板拉伸试验，根据全面屈服准则和COD参量直接研完和评定了焊接构件中的表面裂纹。

Secondly, the essential conditions yielding respectively the simultaneous and sequential modes of play under endogenous timing are analyzed in a general duopoly game.
