考虑应力松弛全场解下Ⅱ型裂纹尖端的塑性区

THE PLASTIC ZONE AT THE CRACK TIP OF MODE Ⅱ CRACK WITH CONSIDERATION OF THE STRESS RELAXATION

本文应用静力学条件，用线弹性全场解代替局部解，给出了考虑应力松弛裂纹尖端的塑性区边界方程，获得了考虑应力松弛下沿任意方向的塑性尺寸．

Based on static conditions and using linear elastic solution of all fields instead of local solution,a boundary expressiong of plastic zone.at the crack tip of mode Ⅱ crack is given withthe stress relaxation taken into consideration.
