Abstract

A small punch testing (SPT)-related stress-strain relation (SPT-SR) model is used to obtain the stress-strain curve of DP600 according to Chen-Cai equivalent energy method. And then the SPT and notched small punch testing (NSPT) specimens were simulated in order to determine the critical fracture criterion of DP600 on the basis of the stress-strain curve obtained by SPT-SR model. Lastly, the J resistance curve of small C-shaped inside edge-notched tension (CIET) specimen for DP600 dual-phase steel was successfully predicted based on the aforementioned fracture criterion.
