In order to fulfill new environmental regulations to reduce Greenhouse Gas Emissions (GHG), new grades of Advanced High-Strength Steel (AHSS) have been replacing conventional steels in vehicle’s body structures. These changes are intended to reduce the estimated total weight, and increase fuel efficiency of vehicles. Although, the implementation of these materials brought new challenges to predict the material response under sheet metal operations. One of the techniques widely used to characterize this behavior is the Forming Limit Curve (FLC), through the Nakazima or Marciniak test. These techniques seem to be not accurate enough, and underestimate the formability limits for AHSS materials in cases where stretching and bending are combined. For this reason, in this study Finite Element simulations were developed to investigate further the effect of the out of plane stress in the FLC determination. Also the investigation of the influence of different lubrication systems was accomplished.
