Abstract In this paper, a comparative investigation of two forming-limit diagram (FLD) models based on the Swift and Hill instability criterion as well as on an empirical model proposed by the North American Deep Drawing Research Group (NADDRG) and experimental FLDs has been carried out for different mild and high-strength sheet steels, such as transformation-induced plasticity (TRIP), dual-phase (DP), austenitic stainless, bake-hardening and interstitial-free (IF) steels.
