Damping
Using the Damping subnode, you can add several types of damping to the material model. Damping can be used in Time Dependent, Eigenfrequency, and Frequency Domain studies; for other study types the settings in the Damping subnode are ignored.
Layer Selection
Select the layer or layers for which this damping model is to be used. The Layer selector inherits the value set in the parent Linear Elastic Material node. When it is set to All layered materials, you cannot access the individual layers.
When the damping model differs between layers, you will need to add several Damping nodes with different layer selections. If the model is the same, and only the material data values differ, you can for most models use a single Damping node with From material. The data for each layer is then received from global Layered Material nodes.

All other settings for the Damping node are described in the documentation for Damping in the Solid Mechanics interface.

For a general description of layer and interface selections, see The Layer Selection Section.
•
You can describe damping values with a through-thickness variation by explicitly or implicitly using expressions containing the extra dimension coordinate as described in Using the Extra Dimension Coordinates.
