In order to predict forming limit curve for stainless steel sheet, the modified maximum force criterion (MMFC), introduced by Hora et al (1996 A prediction method for ductile sheet metal failure in FE-simulation Proc. Numisheet’96 Conf. pp 252–256), was adopted follow Swift’s hardening law. After comparing with experimental results, the improvement of MMFC model for FLD’s prediction were proposed based on Swift’s hardening law by representing work hardening coefficient as a function of strain ratio (β). The proposed MMFC model shows in good agreement between FLD’s computational and experimental result for stainless steel sheet. The results of proposed MMFC model also show that the stress-strain curves of sheets materials are difference at each strain ratio.
