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)

摘要: 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.Abstract: The results in Ref.[1] are not suitable for the cases of β≥2.For this reason,byusing the methods in Ref [1] and Ref [2],we derive the general expressions ofamsotropic plastic fields at a rapidly propagating plane-stress crack-tip for both thecases of β=2 and β>2.
