In this paper a relationship between the critical crack tip opening displacement (CTOD) at crack initiation S,, and the stress triaxiality a,,,/6 is derived based on the damage mechanics criterion for ductile fracture, and a modified crack tip parameter 6: and a modified CTOD criterion are proposed.
