Abstract:Some new developments in a finite element code for the deep drawing process are presented
in this paper. First the phenomenon of friction is treated. A Stribeck friction model has been
developed which accounts for the dependency of the friction coefficient on the local contact
conditions. Secondly a new yield criterion has been developed by Vegter. This Vegter yield
criterion is based on multi-axial stress states. Finally attention will be paid to reduce the CPUtime
of a simulation when drawbeads are used. An equivalent drawbead model has been
developed to avoid an enormous increase in calculation time.
