Abstract

We present a comprehensive experimental-numerical study of cold bending process of a class of dual phase high strength steel (DP1000). The aim of this study Is to perform a strong advanced numerical tool to predict damage in bending process. In the experimental side, a comprehensive experimental study for bending in different rolling direction has been carried out. The experiments were conducted till fracture appears. Enhanced measurement techniques have been used to measure local and global fields as plastic strain distribution In the sheet during the deformation and global force-displacement curves. From numerical point of view, an advanced numerical procedure Is presented. This numerical approach is based on fully coupled constitutive equations accounting for mixed nonlinear isotropic hardening strongly coupled with Isotropic ductile damage. To this end, the models are implemented as VUMAT subroutines for ABAQUS/EXPLICIT. Promising results are obtained which qualitatively are compatible with the experiments.
