OS-E: 0175 Continuum Shell Composites Using PCOMPLS
The PCOMPLS entry can be used to define continuum shell composites
using solid elements. Currently first order CHEXA and
CPENTA solid elements are supported.

Model Files
Before you begin, copy the file(s) used in this example to
your working directory.
Conduct a continuum shell composite analysis of a bracket using PCOMPLS
entry. A force is applied on the RBE2 element and the other end of the
bracket is fixed at all degrees of freedom (Figure 1).
In addition to shell-based composites (via PCOMP,
PCOMPP, or PCOMPG), solid elements using
CHEXA and CPENTA elements can now be used to define
composite elements using the PCOMPLS entry. Multiple plies can be defined
on the PCOMPLS entry referencing corresponding materials, thicknesses,
and ply orientations. The current model under consideration consists of 7 plies with
different thicknesses and orientations. All plies reference the MAT9OR
material entry for orthotropic material entries.
