v6.04.265 SSNV265 — Model GTN: germination under deviatoric loading

Summary:

The purpose of this test is to validate the integration of porosity linked to germination. A purely deviatoric loading makes it possible to cancel the porosity associated with the growth of cavities, which makes it possible to show analytical solutions. The problem is implemented at the hardware level (SIMU_POINT_MAT): it is directly the \(T\) constraint that is imposed by making sure to remain in a positive work hardening regime.
