v7.33.101 WTNA101 — Undrained triaxial test with Drucker Prager softening behavior

Summary:

This test case makes it possible to implement a triaxial non-drained test on two different models during a non-linear calculation. This makes it possible to highlight the effect of negative, parabolic or linear work hardening, in the case of the 3D_HM model.

Modeling A:

• « DRUCK_PRAGER » type model with linear negative work hardening for \(2\mathit{MPa}\) confinement.

• 3D modeling_ HMavec of HEXA20 meshes.

Modeling B:

• « DRUCK_PRAGER » type model with parabolic negative work hardening for \(2\mathit{MPa}\) confinement.

• 3D modeling_ HMavec of HEXA20 meshes.

C modeling:

• « DRUCK_PRAG_N_A » type model with parabolic negative work hardening for \(2\mathit{MPa}\) confinement.

• 3D modeling_ HMavec of HEXA20 meshes.
