| Abstract: | In this paper, we introduce a new fracture criterion in order to solvecrack propagation problems, Based on the generalized Von M ises yield crite-rion, the singular stress field near a crack tip is adopted, A new criterionis obtained, Its result is coincided with Ref,(1).The concept is clear,and the method is simple and convenient |
