A methodology for stress-based forming limit analysis has been developed for advanced high strength steel (AHSS).It was proposed that localized necking occurs when a critical normal stress condition is met.Using a basic,isotropic material model (von Mises,power law hardening),the criterion was applied to various 980 Class AHSS.A Visual Technique to Determine the Forming Limit for Empirical relations have been established to predict the position of the Forming Limit Curve (FLC) in strain space for many grades of automotive sheet steel.Nevertheless,experimental FLC determination continues to be required not only for new materials (new generation high strength steels,aluminum alloys,etc.) but also to evaluate manufacturing processes where a prestrain is applied prior to the final(PDF) Experimental determination of the failure surface Experimental determination of the failure surface for DP980 high-strength metal sheets considering stress triaxiality and Lode angle February 2019 International Journal of Advanced Manufacturing
