Study on springback in deep drawn tailor welded blanks

Résumé

Tailor-welded blanks have strength and thickness mismatch leading to non-uniform deformation imposing complex stress states in the formed part. In this study, numerical simulations are performed to determine the stress states and their influence on the springback behavior of deep-drawn tailor-welded blanks. The tailor-welded blank models consisting of different steels were simulated and the springback is evaluated using split ring test. The results provide an insight on the material combination and weld region location on the springback of TWB´s. The tailor-welded blanks subjected to same forming conditions may result in different springback behavior, depending on the material combination and the blanks orientation. The springback also depends on the section geometry and location of the splitting region in the formed part. Increasing section modulus significantly reduces the springback behavior in a blank.
