v6.04.268 SSNV268 — Multiaxial solicitation of the KICHENIN_NL law: plastic part

Summary:

The purpose of this test is to validate the algorithm for integrating the law of behavior KICHENIN_NLpour with its elastoplastic part: the behavior relationship is then limited to an elastoplastic law with linear kinematic work hardening. The problem studied corresponds to a material point. The results are compared to those obtained with law VMIS_CINE_LINE for a particular loading.

The problem is only implemented in 3D (modeling A) insofar as the programming of the behavioral relationship does not depend on the spatial dimension and there is no specific formulation either for plane constraints or for 1D.
