Описание
Creates a nonlinear mechanical material. Currently, only plasticity with simple (isotropic) hardening is available.
Применение
- To create a new MaterialMechanicalNonlinear object do the following:
- Add a Material for solid first and select it.
- Click the Nonlinear mechanical material button or choose the Model → Materials → Nonlinear mechanical material option from the menu.
- To edit an existing MaterialMechanicalNonlinear object:
- Select it in the Tree view.
- Select the material model (currently, only simple hardening is available).
- Define yield points (stress [MPa] vs plastic strain). The first point must have a zero plastic strain. Press the ... button next to ДанныеYield Points to input the points using a user-friendly list. The syntax is described in the Notes section.
Notes
- 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.
- The syntax should be:
stress_1, 0 stress_2, plastic_strain_2 ...
- With dot as the decimal separator since that's what CalculiX uses.
- For example to define a bilinear model with hardening for S275 steel:
275, 0 490, 0.2
- Or, to define perfect plasticity with no hardening for this material:
275, 0
