| Abstract: | 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. The expression of stress and strain at the tip of the notch is finally derived. |
