The ultimate aim of this work is the development of methods for the simulation of manufacturing process chains such as forming→cutting→heat treatment→joining, providving maximal efficiency without significant loss of accuracy. In the current work, we make the first step in this direction by considering the case of forming of the new high strength steel LH®800. The work begins with a characterization and metallographic investigation of this new steel. Following this, a combined hardening model appropriate for this steel is formulated and identified. The identified model is then validated with the help of the finite‐element simulation of draw‐bending. On this basis, the model was then used to simulate cup deep‐drawing. This process was also simulated with a so‐called one‐step solver which is much faster than the finite element simulation. The results of these two simulations are compared with the results of the deep‐drawing experiment.
