v6.04.197 SSNV197 - Triaxials drained with Hujeux’s law#
Summary
A triaxial calculation in pure mechanics is carried out (equivalent to drained hydraulic conditions) with Hujeux’s law. The calculated solutions are compared to results from the finite element code GEFDYN from École Centrale Paris. The first four models of this test are carried out with a small deformations hypothesis (DEFORMATION =” PETIT “):
the test piece is recommended up to \(50\mathit{kPa}\) (overconsolidated state);
the test piece is recommended up to \(100\mathit{kPa}\) (moderately consolidated state);
the test piece is recommended up to \(200\mathit{kPa}\) (normally consolidated state);
the test piece is recommended up to \(100\mathrm{kPa}\) (normally consolidated state), but a sample with sliding planes (linked to the deviatory mechanisms) inclined by \(45°\) with respect to the vertical is used;
The following three tests repeat the same tests with large deformation kinematics provided by the operator GDEF_LOG :( DEFORMATION =” GDEF_LOG “):
the test piece is recommended up to \(50\mathrm{kPa}\) (overconsolidated state);
the test piece is recommended up to \(100\mathit{kPa}\) (moderately consolidated state);
the test piece is recommended up to \(200\mathit{kPa}\) (normally consolidated state);
