Elastoplastic Analysis of Holed Plate

Application ID: 244

In this example you analyze a perforated plate loaded into the plastic regime. In addition to the original problem, which you can find in section 7.10 of The Finite Element Method by O.C. Zienkiewicz, you can also study the unloading of the plate. The example also shows you how to apply an external hardening function based on an interpolated stress-strain curve.
