1) three dimensional notch
三维切口
1.
The singularity of stress and strain at the tip of three dimensional notch is analysed by the power expansion method, the eigen equation of the notch is gained by the boundary conditions of the notch, the eigenvalues under different inner angles of the notch are solved.
本文利用双重幂级数展开法分析三维切口尖端应力应变奇异性，通过切口边界条件导出切口特征方程，进而求得不同切口内角下特征值序列解答，最后推得切口尖端应力应变场。
2) Three-incision
