Efficient Elasto-Plastic Simulation

Summary

In this paper we describe a method for the construction of radial return algorithms to the plasticity models discussed in Alber [1]. For the classical examples this shows that the algorithms in Simo-Hughes [5] can be derived by this method in a systematic way. We apply the method to viscoplasticity with nonlinear isotropic and kinematic hardening. The combination of parallel multigrid methods with the radial return algorithm results in a very efficient algorithm. The performance of the method is illustrated by a numerical example.
