Modeling a composite laminated shell requires a surface geometry (2D), in general called a base surface, and a Layered Material node which adds an extra dimension (1D) to the base surface geometry in the surface normal direction. You can use the Layered Material functionality to model several layers stacked on top of each other having different thicknesses, material properties, and fiber orientations. You can optionally specify the interface materials between the layers and control mesh elements in each layer.

|
From a constitutive model point of view, you can either use the layerwise theory based Layered Shell interface, or the Equivalent Single Layer theory based Layered Linear Elastic Material node in the Shell interface.
