FEM MaterialMechanicalNonlinear

Description

Adds nonlinear mechanical material model. Currently only plasticity with simple hardening is available.

Usage

1. To define nonlinear mechanical material model do the following:
   • Add the MaterialSolid first and select it.
   • Click the FEM MaterialMechanicalNonlinear button or choose the Model → Materials → Nonlinear mechanical material‏‎ option from the menu.
2. To edit an existing MaterialFluid object:
   • Click it in the Tree view.
   • Select the material model (currently only simple hardening is available).
   • Define yield points (stress vs plastic strain). The first point must have a zero plastic strain specified. Currently only 3 yield points can be defined.
