In this study, we conducted a series of s-rail forming tests by using sheet sheets with the grades of 340, 440, 590，and 780MPa and then compared formability as well as springback behaviors in the final s-rail products. Various types of drawbeads, i.e. without-bead, locking-bead, and smooth-bead, were applied to the s-rail forming die in order to examine the effect of bead on the s-rail formability and springback. The dimensions of experimentally obtained s-rail products were measured for comparison with finite element predictions. From the comparison, we could confirm that the experimental deformation behaviors agreed well with the finite element predictions in terms of the dependence on sheet sheet grade. The quantitative data of formability and springback for different grades of sheet sheets would be very useful for developing car body parts using high strength steel sheets which are increasingly required by automakers recently.
