Distributions of the stress and the strain in the vicinity of crack tip were also studied by three dimensional finite element analysis. It has been shown that the steel with higher yield ratio, comparing with the lower one, has the lower brittle initial CTOD δc , because of the higher stress level in the vicinity of its crack tip; but it has better ductile fracture resistance, because the micro strength heterogenity in the lower yield ratio dual-phase steel causes strain concentration.
