SPRINGBACK SIMULATION FOR AUTOMOTIVE BODY COMPONENTS USING HIGH STRENGTH STEELS
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 modelling 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 spring back simulation. In order to determine the material parameter, impact on springback results is shown. The effect of modelling a more complex material behaviour 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.
