Mechanical Damping
The Mechanical Damping subnode allows you to model mechanical losses in the Piezoelectric Material, Layered either using loss factor material data for the stiffness, or in the form of Rayleigh proportional damping.
Shell Properties
Select the layer or layers for which this damping model is to be used.
When Use all layers is not selected.
When the damping model differs between layers, you will need to add several Mechanical 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 Mechanical Damping node with From material. The data for each layer is then received from global Layered Material nodes.
All other settings for the Mechanical Damping node are described in the documentation for Mechanical Damping in the Solid Mechanics interface.
