In this study. The forming behavior of Tailor welded HS and IF steel S-rail stamping is analyzed by experiments. According to the results. Blank holding force in the formed part is most important to prevent springback. Twist angle and wrinkle formation. The S-rail must have good characteristic of energy absorbing for reducing the severe deformation of passenger compartment. For that purpose. TWB IFHS and HSIF model were calculated by finite element method. In these results. IFHS model absored more energy then that HSIF model.<br/>
