The Linear Elastic Material node adds the equations for a linear elastic layered shell and an interface for defining the elastic material properties. When working with layered shells, you almost invariably take the material data from what has been defined using Layered Material Link, Layered Material Stack, or Single Layer Material nodes. It is however possible to override some data from a Linear Elastic Material node too.

In order to have a correct model, all layers must have been assigned material data for all boundaries selected in the settings for the interface. The override rules for the material models in the Layered Shell interface cannot enforce this, in the same way as for other physics interfaces. You can have several Linear Elastic Material nodes with the same (or partially overlapping) geometrical selections, but with different layer selections.

By adding the following subnodes to the Linear Elastic Material node you can incorporate many other effects:

Data given in the other sections of this node applies to all layers. Thus, if you enter material data explicitly, rather relying on the default From material option, you will override that material property for all selected layers.
