In this paper, the forming limit of a multilayer metallic steel sheet is numerically investigated. Multilayer metallic sheets are an emerging sheet metal that is designed to achieve both high strength and enough formability, which is seriously demanded especially from the automotive industry. Unfortunately, its mechanism of enhanced ductility, fracture behavior, and forming limits have not been sufficiently studied. Therefore, a new stress-strain curve formula is constructed so as to precisely predict the forming limit that is influenced by the unique characteristics of the multilayer metallic sheets. Tensile and stretching experiment on a 15-layer multilayer metallic sheet is conducted, then the results are used to verify the effectiveness of the presented stress-strain expression, and the predicted forming limits are compared to the experimental value, resulted in a good agreement.
