Özet

The rigid-plastic finite element analysis of metal forming processes is known to be much more efficient and stable than the elastic-plastic one. This efficiency results from the absence of kinematical nonlinearities in the formulation. Contact algorithms used in rigid-plastic models must agree with this fact, otherwise the efficiency can be damaged seriously.
