Numerical Simulation on Stamping of Laser Tailor Welded Blank

The stamping process of the tailor-welded blank was simulated by DYNAFORM software.The finite element model of a boxy part was founded,and the formability of tailor-welded blank with different thickness and material was studied.Meanwhile,the influence of weld seam on forming of the part was discussed.The results show that the weld seam model founded by real properties can describe the plastic deformation and strain distribution exactly in the forming process.
