摘要: 文献[1]的结果对α≥2情形不适用。为此,我们用文献[1]的方法导出了α=2和α>2两者的静止平面应力裂纹尖端的各向异性塑性应力场的一般表达式。作为实例,我们给出了α=2的静止平面应力Ⅰ型和Ⅱ型裂纹尖端的各向异性塑性应力场的解析表达式。Abstract: The results in ref. [1] are not suitable for the cases of α≥2, For this reason, we use the method in ref. [1] to derive the general expressions of the anisotropic plastic stress fields at a stationary plane-stress crack-tip for both of the cases of α=2 and α>2. As an example, we give the analytical expressions of the anisotropic plastic stress fields at the stationary tips of mode Ⅰ and mode Ⅱ plane-stress cracks for the case of α=2.
