Abstract. In former papers methods to join different aluminium or different steel plates having same thicknesses are presented. These blanks are often joined by friction stir welding using flat tools. In order to increase the lightweight potential, the Materials Testing Institute of the University of Stuttgart developed a modified friction stir welding process to join aluminium and steel plates of different thicknesses. The process differs from the conventional method in stir welding tool used, which consists of a stepped welding pin and enables combined lap-and-butt joints to be produced. In this paper, a suitable material model is presented to describe this weld seam, allowing the forming behavior of hybrid sheet metal compounds to be realistically simulated.
