v6.04.184 SSNV184 - Triaxial test with the modified Hoek-Brown model

Summary

This test makes it possible to validate the Hoek-Brown elasto-plastic behavior law modified in rock mechanics. It is a triaxial test for which the calculations are carried out using pure mechanics. Three levels of confinement are applied: \(5\mathrm{MPa}\), \(12\mathrm{MPa}\) and \(25\mathrm{MPa}\). For reasons of symmetry, only one eighth of a sample subjected to a triaxial test is considered.

It is a non-regression test.
