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 [R3.07.02].

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

• shells with rotational symmetry around the \(\mathit{OY}\) axis,

Thermomechanical calculations are linked using the finite elements of thermal shells (see [U3.22.01]).
