**v6.04.223** SSNV223 - Elementary validation of the ENDO_SCALAIRE law and the PRED_ELAS management for modeling GRAD_VARI
===============================================================================================================================

**Summary:**

The purpose of this test is to validate the algorithm for integrating the ENDO_SCALAIRE behavior law with a gradient of internal variables as well as the PRED_ELAS control available for this law. The problem studied corresponds to a stress with imposed homogeneous deformation for which an analytical solution can be obtained.

The various models treated are as follows:


* **Modeling A** (:math:`\mathrm{2D}`): We use modeling D_ PLAN_GRAD_VARI.


* **B Modeling** (:math:`\mathrm{3D}`): 3D modeling is used_ GRAD_VARI.
