| 摘 要： | 采用复变函数方法，研究了I型弯折裂纹的平面弹性问题，通过引用适当的保角映射和特殊应力函数，得到了弯折裂纹尖端I型问题应力强度因子的解析解．结果表明，当β=0时，这个结果可以还原到最简单的直线裂纹的情况．

| Abstract: | Dealing with the elastic problem about bent crack by quoting stress function and choosing the technique of conformal mapping with complex variable method of material fracture.The analytical solutions of the stress intensity factors at the crack tip are deduced for mode problems at the crack tip.The results show that: when β=0,the results can reduce to the most simple condition. |
