Viscoelasticity
Use the Viscoelasticity subnode to add viscous stress contributions to an elastic material model.
Shell Properties
Select the layer or layers for which this viscoelastic model is to be used.
Table 6-5: Layer Selections; Viscoelasticity.
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 viscoelastic model differs between layers, you will need to add several Viscoelasticity nodes with different layer selections.
If the same layer is selected in two Viscoelasticity nodes being active on the boundary, then there will be two viscoelastic contributions.
•
All other settings for the Viscoelasticity node are described in the documentation for Viscoelasticity 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.
