Mullins Effect
Use the Mullins effect subnode to define the properties for modeling the stress-softening phenomenon under cyclic loading. The Mullins effect can be used together with Hyperelastic Material.
Shell Properties
Select the layer or layers for which this Mullins effect model is to be used.
Table 6-6: Layer Selections; Mullins effect
Selection
Use All Layers
Selection of Individual Layers
Boundary
Same as parent selection when the node is added.
When Use all layers is not selected.
Only a subset of the layers selected in the parent can be selected.
If the Mullins effect model differs between layers, you will need to add several Mullins Effect nodes with different layer selections. If there are two Mullins Effect nodes where the same layer is selected on the same boundary, the latter will be overridden on the common selections.
•
All other settings for the Mullins Effect node are described in the documentation for Mullins Effect in the Solid Mechanics interface.
•
For a general description of layer and interface selections, see The Shell Properties and Interface Selection Sections.
•
You can provide material parameters with a through-thickness variation by explicitly or implicitly using expressions containing the extra dimension coordinate as described in Using the Extra Dimension Coordinates.
