Experience from Using a New Material Model for Stainless Steels with TRIP-effect
This paper presents experience from using a recently developed material model for austenitic stainless steels with TRIP-effect for simulation of sheet metal forming. Results from two different forming operations are presented. In materials with TRIP-effect, a phase transformation from austenite to martensite occurs during forming that significantly affects the hardening behavior. The effect is sensitive to the amount of straining as well as the temperature. For materials that have a strong TRIP-effect new forming techniques are possible that can lead to very light and strong components. The material model for austenitic stainless steel sheet exhibiting the TRIP-effect has been implemented in LS-DYNA.
