Automotive manufacturers around the world are pushing towards the goal of better safety from their vehicles without compromising on the fuel economy. One of the very successful efforts in this direction is the hot forming technique that has been around for 30 years since Saab used it for the first time in 1986. Finite element simulations for this technique are of paramount importance to identify and optimize the process; as the steels used in hot stamping are sensitive to certain variables when heated that would otherwise cause very few disturbances in a normal cold forming process. The major contributor to the high strength of the stamped part is the phase transformation that it undergoes during the hot forming process. This paper investigates and identifies critical parameters through Finite Element Analysis (FEA) simulations.
