The article of authors  deals with the design of the structural part of the bodywork in the CAE system CATIA using the CAE software solutions of the AutoForm system, which are based on the finite element method. This design was subsequently implemented into the design of dies in order to achieve the most efficient and high-quality dies, which are increasingly required in industrial practice for lifetime and functionality. Three types of high-strength steels TRIP HCT780T, DP-HCT780X and CP-HCT780C with approximately the same tensile strength were selected for the experiments. Based on the input parameters, simulations were implemented and the results obtained from the simulations will be the basis for selecting the most optimal variant. The main measurable and evaluative factor was the outputs obtained from the FLD diagrams.
