✦ Synopsis

The eigenfunction expansion variational method (EEVM) is proposed to determine the stress intensity factors for two-dimensional cracked bodies. In the new method, the undetermined coefficients in the truncated eigenfunction expansion form are determined by using the variational method. It is expected that the uncertainty initiated in boundary collocation scheme can be avoided. Several numerical example\ are given. which can prove the efficiency of the EEVM method.
