摘要：

A modified "moving singular element method" used to simulate the process of dynamic crack propagation, called "quasi-static method", is presented in this paper. The dynamic stress intensity factor of the crack propagation is calculated by using both full dynamic method and quasi-static method. The results show that the present method takes about 25% less CPU time than the full dynamic analysis and it has a reasonable accuracy.
