1. Introduction

In the following, we are interested in the mechanical modeling of thin structures with an average surface of particular geometry: shells with symmetry of revolution around the \(\mathit{Oy}\) axis

More particularly, we are limited to the case where the mechanical parameters (materials, loads) are independent of a direction of space (the circumference for shells of revolution).

For the resolution of linked thermomechanical problems, one must first use the finite thermal shell element described in [R3.11.01] as appropriate in its axisymmetric version.

First of all, a review of the mechanical model is presented below: kinematics, law of thermoelasto-plastic behavior. Then the selected finite element, the interpolation and the integration method are presented.

Finally, some numerical application results are given, in comparison with analytical solutions.
