Evaluation of two mutliscale models for the simulation of cross-die forming of Dual Phase (DP) steels
Source abstract
Abstract
Two micro-macro modelling approaches, one based on crystal plasticity and the other on a Mori-Tanaka mean-field model, are presented and used for the simulation of forming operations on dual phase (DP) steels. The material parameters are determined based on bending-unbending experiments while deep-drawing with a cross-shaped die is simulated based on user-defined material laws (UMAT) in the ABAQUS finite element code. It is demonstrated that accurate predictions would require a combination of both modelling approaches.
