Several nonlinear material laws are delivered with GeoDict and may be conveniently set up in the GeoDict Material Database dialog. See the Material Database User Guide for more information.

The available nonlinear material laws are: Elasticity, Plasticity, Damage, Viscosity and Failure. All these material models are only available for the deformation type Without Geometric Nonlinearity.

These material laws can be combined in different ways:

• Plasticity, damage, and viscosity can be combined. For these combinations, only the exponential damage model is available.
• The Mazars damage model cannot be combined with any other model.
• The Failure model cannot be combined with any other model.
