Springback Prediction with FEM Analysis of Advanced High Strength Steel Stamping Process

In many manufacturing processes involving sheet metal fabrication, springback is a major concern that makes tool design a very complex task. New demands have led to an increase in the use of Advanced High Strength Steel (AHSS) as work material. An increase in strength decreases the formability of the material and increases the springback behaviour. The aim of the numerical simulation carried out in this paper is to verify the stamping process and the shape of the final component for studying springback of AHSS. Finally, a test case of a simple profile stamping process was analysed using the incremental approach of the AutoForm 4.04 Incremental software code for two different AHSS materials: Dual-Phase (DP 600) and Transformation-Induced Plasticity (TRIP 800)
