Springback Simulation for Automotive Body Components using High Strength Steels 2003-01-2868
The objective of this study is to develop a more precise springback prediction technique by means of finite elements method for the optimization of forming process design. The approach includes a new material modeling method to calculate accurate residual stresses inherent in forming processes, and a new analytical method to calculate springback shape by releasing residual stresses in a sequence of releasing steps.
This paper proposed the new analytical method in springback simulation for actual automotive components with complex shapes. A new algorism, Multi-Step-Springback method was developed to improve the accuracy of springback simulation. In order to determine the material parameter, compression-tension tests were carried out. The impact on springback results is shown. The effect of modeling a more complex material behavior is presented. The simulation using proposed material model shows good accuracy of springback prediction for hat-shape drawing, a typical cross-section for structural members.
