v7.31.133 WTNV133 — Undrained triaxial with Hujeux’s law

Summary

This test makes it possible to validate the implementation of monotonic deviatory mechanisms and the cyclical consolidation mechanism of Hujeux’s law. This is a triaxial test carried out in an undrained condition. The hydraulic coupling is taken into account, the sample is completely saturated, the skeleton and the fluid are assumed to be incompressible.

The lockdown levels applied are \(50\mathrm{kPa}\) and \(200\mathrm{kPa}\).

The results obtained with Hujeux’s law are compared with results from the finite element code GEFDYN from École Centrale Paris.
