v6.04.263 SSNV263 — Non-linear isotropic work hardening plasticity VMIS_ISOT_NL under triaxial loading and shearing

Summary:

The purpose of this test is to validate the algorithm for integrating the law of behavior VMIS_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.

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
