| 摘 要： | 本文分析了Neuber关系的推导过程,描出Neuber关系,即使对Ⅲ型加载问题也不是解析解。本文根据弹塑性断裂力学理论,对幂强化材料,导出了Ⅲ型加载裂纹问题弹塑性应力应变集中关系。同时分折了Ⅰ型缺口弹塑性应力应变集中关系。

| Abstract: | Neuber s formula is analyzed in this paper. It is found that Neuber s formula is not an analytical solution even to the antiplane shear loading problem. By using the theory of elastic-plastic fracture, an elastic-plastic stress-strain concentration formula is obtained for antiplane shear loading crack problem of power hardening materials. |
