Deep drawing simulations of tailored blanks and experimental verification

Tailored Blanks are increasingly used in the automotive industry. A combination of different materials, thickness, and coatings can be welded together to form a blank for stamping car body panels. The main advantage of using Tailored Blanks is to have specific characteristics at particular parts of the blank in order to reduce the material weight and costs. To investigate the behaviour of Tailored Blanks during deep drawing, the ®nite element code DiekA is used. In this paper, simulations of the deep drawing of two products using Tailored Blanks are discussed. For verification, the two products are stamped to gain experimental information. The correlation between the experimental results and the simulation results appears to be satisfactory
