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

Key words: Fracture criterion Yield criterion New method
