The ply thickness is typically defined as the final cured thickness of a single ply
of material. The ply can be made of any material: isotropic, orthotropic,
anisotropic, or any other material law.
The thickness applies to all elements in the ply shape. Thickness can additionally be
modified spatially, element by element, using a drape table assigned to the ply.
The following image shows a typical ply thickness. Figure 1.
