Abstract

Tailor-welded blanks of V-shape free bending process and springback were analyzed by finite element method, Experimental result were adopted to confirm the result of FEA. Models for V-shape free bending of Tailor-welded blanks and welded seams in transverse or longitudinal direction were accurately created using shell element. Combined the experimental result and that from finite element analysis, the displacement of the seam of the welded blanks in the V-shape free bending process was found, and also the effecting law of springback by the geometry parameter of the die, the property of the material, different thickness of tailor-welded blanks, friction of the interface between module and blank etc. The work can be a basis to the springback control of tailor-welded blanks.
