Recent developments in finite element simulations of the deep drawing process
Meinders, T. and Carleer, B.D. and Vegter, H. and Huetink, J. (1997) Recent developments in finite element simulations of the deep drawing process. In: Sheet Metal 1997, 8 - 10 April 1997, Ulster, United Kingdom.
|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.
