v6.04.267 SSNV267 — Multiaxial stress from the KICHENIN_NL law: viscoelastic part

Summary:

The purpose of this test is to validate the algorithm for integrating the law of behavior KICHENIN_NLpour, its non-linear viscoelastic part. The problem studied corresponds to a material point; the mode of solicitation is such that there is an analytical solution, including in the non-linear case.

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.
