The influence of the rolling direction of the joined steel sheets on the springback intensity in the case of Ω-shape parts made from tailor welded strips

The final shape of the draw bended parts is seriously affected by the springback phenomenon. The present work deals with numerical simulation and experimental tests related to draw bending and springback of Ω-shape parts manufactured from tailor welded stripes and it is trying to prove out the important role that the rolling direction of the joined steel sheets has on the springback intensity. The experimental tests and the simulation by finite element method (ABAQUS) have been carried out using two different rolling directions and maintaining constant all other parameters.
