**v6.04.264** SSNV264 — Non-linear isotropic work hardening viscoplasticity VISC_ISOT_NL under triaxial loading and shear
=================================================================================================================================

**Summary:**

The purpose of this test is to validate the algorithm for integrating the law of behavior VISC_ISOT_NL. The problem studied corresponds to a hollow cylinder subjected to a state of triaxial stress + shear whose components are constant (in space) in the cylindrical coordinate system. This is the viscoplastic version of the test described in [:ref:`V6.04.263 <V6.04.263>`] which was limited to plasticity independent of the loading speed.

The problem is implemented:


* in AXIS_SIdans modeling A


* in AXIS_GRAD_VARI in B modeling


* in 3D in C modeling


* in 3D_ GRAD_VARI in 3D modeling
