Thermal Expansion (for Materials)
Use the Thermal Expansion subnode to add an internal thermal strain caused by changes in temperature.
You can provide a temperature with a through-thickness variation by explicitly or implicitly use expressions containing the extra dimension coordinate as described in Using the Extra Dimension Coordinates.
Layer Selection
Select the layer or layers for which this thermal strain contribution is to be added. 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.
If the Input type differs between layers, you will need to add several Thermal Expansion nodes with different layer selections. If only the material data values differ, you can use a single Thermal Expansion node with From material. The data for each layer is then received from global Layered Material nodes.
If the same layer is selected in two Thermal Expansion nodes being active on the same boundary, the second definition will override the previous.

All other settings for the Thermal Expansion node are described in the documentation for Thermal Expansion (for Materials) in the Solid Mechanics interface.

You can provide parameters for the expansion with a through-thickness variation by explicitly or implicitly using expressions containing the extra dimension coordinate as described in Using the Extra Dimension Coordinates.
