- Abstract:The biaxial tensile tests were carried out to investigate the deformation behavior and yield loci of dual-phase (DP) steel sheets under biaxial tensile conditions.The true stress-true strain curves of DP steel sheets for different loading ratios were obtained,and the experimental yield loci were determined based on the equivalent plastic work principle.The experimental yield loci were compared to the theoretical yield loci based on Hill48,Hill90,Hill93,Hosford,Barlat89,Yld2000-2d and Gotoh yield criteria.It is found that Yld2000-2d yield criterion can describe the general trends of experimental yield loci of DP steel sheets with comparably higher accuracy.Hosford criterion has the maximum error for DP590,whereas Hill48 and Barlat89 have the maximum errors for DP780 and DP980.
