**v7.12.303** HSLA303 - Cylinder under pressure and thermal expansion
=======================================================================

**Summary:**

The calculation is carried out axisymmetrically. The aim of the test is to validate the pre-deformations (keyword PRE_EPSI).

The cylinder is subjected to homogeneous thermal expansion (:math:`\Delta T` constant).

The procedure followed is as follows:


* let :math:`{\varepsilon }_{1}` be the field of deformations resulting from a first calculation, the cylinder being subjected to homogeneous thermal expansion :math:`\Delta T` (:math:`{U}_{1}` the field of resulting movements),


* in a second calculation, the cylinder is subjected to internal pressure, with the deformation field :math:`{\varepsilon }_{1}` as pre-deformations (i.e. :math:`{U}_{2}` the resulting displacement field),


* the results are then compared with field :math:`U`, obtained with a cylinder under pressure, but without pre-deformations. We have to have the relationship: :math:`{U}_{2}\mathrm{=}U+{U}_{1}`.
