v6.04.211 SSNV211 - Drained triaxial test with model VISC_DRUC_PRAG

Summary

This test makes it possible to validate model VISC_DRUC_PRAG based on the elastoplastic Drucker-Prager model. Creep is taken into account by a Perzyna power law. It is a triaxial test in pure mechanics or under drained conditions. The calculations are carried out only on the solid part of the soil without hydromechanical coupling. A lockdown level of \(5\mathit{MPa}\) is being applied. For reasons of symmetry, only one eighth of a sample subjected to a triaxial test is interested in. The modeling is axisymmetric.

It is a non-regression test.
