Beschreibung

Creates a nonlinear mechanical material. Currently, only plasticity with simple hardening is available.

Anwendung

  1. To create a new MaterialMechanicalNonlinear object do the following:
  2. To edit an existing MaterialMechanicalNonlinear object:
    • Select it in the Tree view.
    • Specify 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.

Hinweise

  • In FreeCAD 0.19 and older versions, only 3 yield points can be specified. Since version 0.20 a list of yield points can contain as many as required.
