摘要：

The application of the dual boundary element method and the path independent J-integral for the evaluation of dynamic stress intensity factors of stationary cracks in a linear elastic material is presented. The distinct set of boundary equations of elastodynamics is obtained by using the dual boundary element method and the dual reciprocity approach. Numerical implementation of the path-independent J-integral and the decomposition technique is presented. The method is applied for several cracked structures and the results are compared with
