The numeric simulation of thermo‐mechanical hot forming processes and the modelling of the structure development and the mechanical properties of complex metallic materials serve for both the optimization of forming processes and the increase of process reliability. To meet close process windows, predictions of the formability of the material as function of the process conditions and material history are required as well. Lifetime evaluation of the tools is made possible from coupled computation of workpiece and tool loads. Material and damage models in use must be adapted on the basis of laboratory experiments and advanced analysis methods.
