**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 :math:`2\mathit{MPa}` confinement.


* 3D modeling_ HMavec of HEXA20 meshes.

Modeling B:


* "DRUCK_PRAGER" type model with parabolic negative work hardening for :math:`2\mathit{MPa}` confinement.


* 3D modeling_ HMavec of HEXA20 meshes.

C modeling:


* "DRUCK_PRAG_N_A" type model with parabolic negative work hardening for :math:`2\mathit{MPa}` confinement.


* 3D modeling_ HMavec of HEXA20 meshes.
