高速扩展平面应力裂纹尖端的各向异性塑性场的补充研究（Ⅰ）

A Supplemtary Study of Anisotropic Plastic Fields at a Rapidly Propagating Plane-Stress Crack- Tip(I)

文献［１］的结果对于β≥２的情形不适用，为此，我们用文献［１］和［２］的方法导出了β＝２和β＞２两者的高速扩展平面应力裂纹尖端的各向异性塑性场的一般表达式。

The results in ref.[1] are not suitable for the case of β≥2. For this. reason,by using the methods in ref . [ 1] and ref.[ 2] ,we derive the general expressions of anisotropic plastic tilds at a rapidly propagating plane- stress crack一tip for both the cases of and β>2
