Description

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

Usage

  1. To create a new MaterialMechanicalNonlinear object do the following:
  2. To edit an existing MaterialMechanicalNonlinear 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.

Notes

  • In FreeCAD 0.19 and older versions, it's possible to specify only 3 yield points. Since the 0.20 version, this limitation doesn't exist and a list of yield point can contain as many of them as needed.
