Investigation of the Material Rolling Direction Influence on Springback Effect of a U-shape Part Manufactured by Tailor Welded Stripes

This paper deals with some numerical simulation and experimental tests related to forming and springback of a rectangular part manufactured from tailor welded blanks. Final shape of the parts manufactured by tailor welded blanks is seriously affected by springback effect. This paper work is trying to prove out the important role of material rolling direction has on the springback reduction. The influence of the material rolling direction on the tailor welded stripes springback is examined using the simulation by finite element method (ABAQUS). Experimental tests have been carried out using different material rolling direction and maintaining constant all other parameters. The resulted parts were measured using a 3D scanning machine. An optimum material rolling direction is established and the results are presented in the final section of this paper.
