“…In this study, a small punch testing (SPT)-related stress-strain relation (SPT-SR) [16] model is adopted to determine the stress-strain curves of DP600 by SPT experiments based on Chen-Cai [17,18] equivalent energy method. After that, a logarithmic fracture criterion is obtained via SPT and NSPT experiments on the basis of the stress-strain curve determined by SPT-SR model.…”

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.
