**u3.12.02** Models COQUE_AXIS
======================================

**Summary:**

This document describes for modeling COQUE_AXIS:


* the degrees of freedom carried by the finite elements that support modeling,


* the related support meshes,


* the loads supported,


* non-linear possibilities,


* test cases implementing the models.

Thermo-elasto-plastic modeling COQUE_AXIS corresponds to a formulation derived from 3D models with shell kinematics [:ref:`R3.07.02 <R3.07.02>`].

They can be used to model structures with an average surface of particular geometry:


* shells with rotational symmetry around the :math:`\mathit{OY}` axis,

Thermomechanical calculations are linked using the finite elements of thermal shells (see [:external:ref:`U3.22.01 <U3.22.01>`]).
