v7.31.134 WTNV134 — Cyclic undrained triaxial with Hujeux’s law

Summary

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

The lockdown level is \(30\mathrm{kPa}\).

The results obtained with Hujeux’s law are compared to results from the finite element code GEFDYNde at École Centrale Paris ( < http://www.mssmat.ecp.fr/-GEFDYN ,016->` http://www.mssmat.ecp.fr/-GEFDYN ,016-`_).

B modeling makes it possible to deal with the same problem with a « hardware point » simulation, without a finite element.
