An extension of the radial return scheme for springback simulation in sheet metal forming

摘要

This paper is mainly concerned with teh numerical simulation of the springback phenomenon that occurs in sheet metal forming when a formed part is ejected from the tooling. In order to simulate this problem as accurately as possible, we use implicit algorithms to integrate both constitutive and equilibrium equations. Numerical simulations such as an U-bending test and the S-rail test are presented in order to demonstrate the efficiency of the proposed procedure.
