Abstract

The plastic behavior of AHSS is still far from being completely understood, and its prediction is of large importance in reliability of forming simulation in present automotive industry [1]. Conventional techniques have been proven to be not accurate enough, and underestimate the formability limits for AHSS materials in cases where stretching and bending are combined. In order to satisfy industrial requirements more work need to be done to understand the formability behavior of sheet metal, and special attention needs to be directed to the possible reasons of the lower predicted formability limits. In previous work [2], experimental results for different materials confirmed the positive effect of bending in terms of formability, and demonstrated the influence of curvature on the FLC is especially clear in the plane strain region. Using conventionally determined FLC could lead to not optimal material consumption during sheet forming operations. For this reason, in this study 3D Finite Element simulations were developed using the commercial code ABAQUS/Standard to investigate further the effect of the out of plane stress, and punch radii for the FLC determination. Also the investigation of the influence of different lubrication systems was accomplished.
