Abstract

Abstract

The singularity of stress and strain at the tip of three-dimensional notch isanalysed by the power expansion method.the eigenquation of the notch is gainedthrough the boundary conditions of the notch, the eigenvalues under different innerangles of the notch are obtained, the expression of stress and strain at the tip of thenotch is finally derived.
- three-dimensional notch,
- singularity,
- fields of stress and strain
