v7.31.146 WTNV146 - Validation of a cohesive law model for the hydromechanical case coupled with XFEM

Summary:

The aim of this test is to ensure the proper functioning of the « Mortar » type cohesive zone model associated with hydromechanical elements coupled with XFEM.

In this test, we test all the operating regimes of the cohesive zone model for the HM- XFEM elements. The cohesive law used is CZM_LIN_MIX (It is the only one available for the HM-XFEM elements). This test is therefore purely mechanical, all the degrees of freedom associated with the fluid phase are locked at zero. Modeling A is two-dimensional while modeling B is three-dimensional.
