Elastoplastic Analysis of Plate with a Center Hole

In this model, a plate containing a hole is loaded to above the elastic limit, where the material is assumed to be elastoplastic with isotropic hardening.

The example is derived from The Finite Element Method by O.C. Zienkiewicz. The model also shows how to apply an external hardening function based on an interpolated stress-strain curve.

Development of plastic region (red) for a load level of 1.08.
