Finite Element Analysis of Springback of a Sheet Metal in Wipe Bending Process

Amul Biradar | M. D. Deshpande

Abstract: This work presents a study of spring back in wipe bending metal forming process. Spring back is one of the most sensitive features of the sheet metal forming, which occurs due to elastic recovery during unloading. The main purpose of this work is spring back prediction of sheet metal copper alloy and investigation into the causes of the spring back, such as process parameter, geometry of tools etc. In this work the prediction model of spring back in wipe bending process was developed using finite element method code ANSYS APDL 14.0 and an over bend approach is applied to compensate the spring back and the obtained spring back for different process parameters are validated by analytical method.

Keywords: Springback, Plasticity, Wipe bending, over bend approach
