Influence of the forming process on springback

Abstract The use of advanced high-strength steels (AHSS) is associated with increased springback and represents a great challenge for today’s press shops regard to the dimensional accuracy cold-formed sheet metal parts. Springback, its appearance characteristics are mainly dependent on stress state introduced by forming process part geometry before opening tools. With aim determining influence springback, simulation used in this contribution analyze hat profile from dual-phase steel (DH1000) three different processes: crash forming, bending drawing. For purpose, stresses generated these processes resulting examined considering respective history. results show strong material flow controlled tool which leads significant differences among increases
