Abstract

From the viewpoint of the constraint intensity in crack tip field-stress triaxiality, the paper reveals the essential reasons of losing of J-dominance of crack tip field, which caused J_IC to depend on the specimen geometries and not a materials constant in plain strain. The effects of stress triaxiality in the crack tip regions on the fracture criterion were discussed. A new elastic-plastic fracture parameter, J_VC = J_IC · f(σ_m/ \ ̄gs), is proposed and proven to be a materials constant independent of the types of specimens geometries.
