.. _V6.04.172: **v6.04.172** SSNV172 — Monocrystalline viscoplastic behaviors ====================================================================== **Summary:** This test makes it possible to validate mono-crystalline behaviors in a uniaxial situation. The geometry processed is a cube, the state of stresses and deformations is homogeneous. In order to best test the laws of behavior, regardless of the definition of sliding systems, a particular, non-physical sliding system is used here, which represents sliding in a single direction. This makes it possible to compare two of the monocrystalline viscoplastic behaviors, (with kinematic work hardening defined by a reminder variable) to the macroscopic viscoplastic behavior of Chaboche. For other behaviors (in particular KOCKS_RAUCH) we only check the non-regression of the results. All these tests are carried out in A (3D) modeling. B modeling makes it possible to validate, again by inter-comparison with Chaboche's law, monocrystalline behaviors in :math:`\mathrm{2D}` (C_ PLAN). .. 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
