==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.

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:
  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.
