✦ Synopsis

The plane elastic problem for a finite plate with a curved crack is considered. Uniform external tension on the outer boundary is chosen as the applied load. The stress intensity factors at the crack tips are calculated by using the boundary collocation method. The results obtained by this method compare favourably with the existing solutions for the infinite cases. Solutions for the finite plates are given to show the effects of the dimensions.
