hermit.fenics.material
======================

.. py:module:: hermit.fenics.material

.. autoapi-nested-parse::

   Constitutive model for the R-M shell.

   Hermit always drives the FEniCSx residual with the ABD stiffness matrices (A, B, D for
   membrane/coupling/bending, plus the transverse-shear ``As``). The isotropic case builds
   A/B/D/As in CSDL upstream (``hermit.csdl_helpers.assemble_abd_isotropic``); composite via
   ``hermit._laminate.compute_clt``. This module just holds them as a CLT tuple for the elastic model.

   Port of ``MaterialModelComposite2`` from the femo dev_coupling branch.
