|Title:||PARAMETERS OPTIMIZATION OF SPRINGBACK IN SHEET METAL FORMING BY RESPONSE SURFACE METHOD|
|Keywords:||Sheet metal forming|
moving least square
|Abstract:||This paper deals with the optimization of Sheet Metal Forming parameters in order to reduce defect of springback which occur at the end of process. We propose a specific methodology based on the coupling between the one-step Inverse Approach as a surrogate model for the rapid simulation of sheet forming process, and a Response Surface Method based on diffuse approximation. The response surfaces are built using Moving Least Squares approximations constructed within a moving region of interest. Application of the sheet metal forming process is used to demonstrate the robustness of the method. The final design is validated with Stampack® and Abaqus® commercial codes based respectively on Explicit Dynamic and Implicit Static Approaches.|
