v6.04.158 SSNV158 - Drained triaxial test with the Lagle model

Summary

This test makes it possible to validate the Lagle model in rock mechanics (formalism CIH). It is a triaxial test under drained conditions. The calculations are carried out only on the solid part of the soil without hydromechanical coupling. Four levels of confinement are applied (\(8\mathit{MPa}\) — \(4\mathit{MPa}\) — — \(2\mathit{MPa}\) — \(1\mathit{MPa}\)). 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.
