.. _V6.04.234: **v6.04.234** SSNV234 - Elementary validation of the ENDO_FISS_EXP 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_FISS_EXP 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. .. toctree:: :hidden: self .. toctree:: :maxdepth: 2 :numbered: Probl_me_de_r_f_rence Solution_de_r_f_rence Mod_lisation_A Mod_lisation_B Synth_se_des_r_sultats
