**r4.01.02** Anisotropic elasticity
==================================

**Summary**

This document treats anisotropic thermoelasticity, used for modeling 3D and 2D continuous media (C_ PLAN, D_ PLAN, AXIS), or the layers of composite shells.

The thermoelastic medium may be anisotropic in 3 directions (one speaks of orthotropic elasticity), or else isotropic in two directions (one speaks of transverse isotropic elasticity), or else it may have cubic symmetry.
