Abstract:

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 TWB is seriously affected by springback effect. This paper work is trying to prove out the important role that blankholder force has on the springback reduction. The influence of the blankholder force on the TWB springback is examined using the simulation by finite element method (ABAQUS). Experimental tests have been carried out using different blankholder force and maintaining constant all other parameters. The resulted parts were measured using a 3D scanning machine. An optimum holding force is established and the results are presented in the final section of this paper.
