Abstract
AbstractIt is possible to pursue a multi‐scale modeling approach for sheet forming simulations by applying the concept of virtual material testing to determine the yield surface from the microstructure of a given material. Full‐field simulations with phenomenological crystal plasticity models are widely used for this kind of investigations. However, recent developments focus on incorporating physical quantities like dislocation density into these models. In this work, a dislocation density based crystal plasticity model is used to investigate the plastic anisotropy of the deep drawing steel DC04. In particular, we focus on the prediction of R‐values, which can be used to calibrate macroscopic plasticity models. (© 2014 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim)
