This section describes how to create a solid composite layup.
In most cases, you should model a composite solid as a shell or continuum
shell composite layup. However, you should use a solid composite layup for the
following cases:
When the transverse shear effects are predominant.
When you cannot ignore the normal stress.
When you require accurate interlaminar stresses, such as near
localized regions of complex loading or geometry.
Solid composite layups are expected to have a single element through their
thickness, and that single element contains multiple plies that are defined in
the ply table. If the region to which you assign your solid composite layup
contains multiple elements, each element will contain the plies defined in the
ply table, and the analysis results will not be as expected.
