Abstract
Exact simulation of hot‐forming processes using the finite element method requires the most precise possible specification of the material parameters and physical boundary conditions prevailing in each case. The report presents a method to supply all the necessary data. New experimental concepts have been developed and applied, particularly for the more complex boundary conditions, which are virtually undocumented in literature. These techniques permit analysis of the real workpiece/interlayer/die combination, supplying reliable data for an FEM simulation.
