v7.31.140 WTNV140 - Anisotropic drained elastic triaxial test

Summary:

This test makes it possible to validate the mechanical part of the transverse anisotropy in THM. It is a triaxial test with zero pressure. This test can therefore be compared with a case of pure mechanics.

The anisotropy coordinate system will be different from the main coordinate system. We test the different geometries (3D, 2D, AXI).

A-modeling is an elastic case in 3D (transverse isotropy) treated in pure mechanics and then in HM.

B modeling is an elastic case in 2D orthotropic treated in pure mechanics and then in HM.

Modeling It is an elastic case in axisymmetry treated in pure mechanics and then in HM.
