Abstract

The influence of reference load case on the crack face weight functions for different finite cracked bodies was investigated by examining the Green's functions which are related to the crack face point force loading. The weight functions were analytically determined based on a general crack opening displacement equation. It was found that the degree of reference-load-case-dependence is not only a function of the reference stress itself, but also the crack length, overall cracked configuration and the number of terms contained in the crack opening displacement equation. Some useful guidelines for the choice of reference load cases in generating the weight functions have been introduced, and the way to improve the weight function accuracy at extended crack lengths recommended.
