v7.31.138 WTNV138 - Undrained triaxial test with model VISC_DRUC_PRAG

Summary

This test makes it possible to validate the VISC_DRUC_PRAG model with hydraulic coupling. It is a triaxial test under undrained conditions. The undrained aspect is modelled by zero volume deformation of the skeleton and the hydraulic coupling is taken into account, the sample is completely saturated, the skeleton and the fluid being assumed to be incompressible.

For reasons of symmetry, only one eighth of a sample subjected to a triaxial test is interested in.

The lockdown level is \(8\mathrm{MPa}\).
