This paper discusses current developments to determine the formability of a material during a crack‐endangering production process. The presentation of the theoretical background is followed by a description of the technology developed at the IBF to investigate the material failure. Characteristic formability limit curves have been plotted from FEM simulations of the basic tests which were performed parallel to the experimental tests. These curves enable the forecast of material failure to be transferred to an industrial process. It is shown that this test technology is valid for both cold and hot forming conditions.
