Viscoelasticity
Use the Viscoelasticity subnode to add viscous stress contributions to an elastic material model. Viscoelasticity can be added to Linear Elastic Material, Layered Linear Elastic Material, Nonlinear Elastic Material and Hyperelastic Material.
If the Composite Materials Module is available, the viscoelasticity model can be applied to arbitrary layers in a multilayered membrane.
Shell Properties
This section is present only when the Viscoelasticity node is used under Layered Linear Elastic Material.
Select the layer or layers for which this viscoelastic model is to be used.
When Use all layers is not 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.
