**v6.04.168** SSNV168 — Drained triaxial test with DRUCK_PRAGER softening behavior
===========================================================================================

**Summary:**

This test case makes it possible to simulate a drained triaxial test on four different models during a non-linear calculation. This makes it possible to highlight the effect of the type of negative work hardening in the case of a AXIS or 3D model.

Modeling A:


* "DRUCK_PRAGER" law of behavior with linear negative work hardening for a confinement of :math:`2\mathit{MPa}`.


* QUAD4 mesh model AXISavec.

Modeling B:


* "DRUCK_PRAGER" law of behavior with parabolic negative work hardening for a confinement of :math:`2\mathrm{MPa}`.


* AXISavec modeling of QUAD4 meshes.

C modeling:


* "DRUCK_PRAGER" law of behavior with linear negative work hardening for a confinement of :math:`2\mathrm{MPa}`.


* 3D modeling with HEXA20 meshes.

D modeling:


* "DRUCK_PRAGER" law of behavior with parabolic negative work hardening for a confinement of :math:`2\mathrm{MPa}`.


* 3D modeling with HEXA20 meshes.

E modeling:


* "DRUCK_PRAG_N_A" law of behavior with linear, parabolic and exponential hardening, for a confinement of :math:`2\mathrm{MPa}`


* QUAD4 mesh model AXISavec.

F modeling:


* "DRUCK_PRAG_N_A" law of behavior with linear, parabolic and exponential hardening, for a confinement of :math:`2\mathrm{MPa}`


* 3D model with HEXA20 meshes.
