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 (\(\mathrm{2D}\)): We use modeling D_ PLAN_GRAD_VARI.

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