利用保角变换和反平面弹性复势方法，得到了尖端尖端裂纹在反平面剪切和扭转载荷作用下应力场的精确解，基于应力场分布，导出了III型裂纹应力强度因子的相关表达式，并利用大量有限元分析结果对其精度进行了详细讨论。
In this work, the exact solution for the stress fields ahead of cracks initiated at sharp notch tips under antiplane shear and torsion loadings is derived in close form, leveraging conformal mapping and the complex potential method for antiplane elasticity.Based on the stress field distributions, relevant expressions for the mode III crack stress intensity factors are derived and their accuracy is discussed in detail taking advantage of a bulk of results from FE analyses.
