Translations:FEM MaterialMechanicalNonlinear/11/en

1. To create a new MaterialMechanicalNonlinear object:
   1. Add a Solid Material.
   2. Select it.
   3. There are several ways to invoke the command:
      • Press the Non-Linear Mechanical Material button.
      • Select the Model → Materials → Non-Linear Mechanical Material‏‎ option from the menu.
2. To edit an existing MaterialMechanicalNonlinear object:
   1. Select it in the Tree View.
   2. Select the material model (isotropic (simple) hardening or introduced in 1.0: kinematic hardening).
   3. Define yield points as true stress [MPa] vs true (logarithmic) plastic strain [-]. The first point must have a zero plastic strain. Press the … button next to DataYield Points to input the points using a user-friendly list. The syntax is described in the Notes section.
