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 \(2\mathit{MPa}\).

  • QUAD4 mesh model AXISavec.

Modeling B:

  • « DRUCK_PRAGER » law of behavior with parabolic negative work hardening for a confinement of \(2\mathrm{MPa}\).

  • AXISavec modeling of QUAD4 meshes.

C modeling:

  • « DRUCK_PRAGER » law of behavior with linear negative work hardening for a confinement of \(2\mathrm{MPa}\).

  • 3D modeling with HEXA20 meshes.

D modeling:

  • « DRUCK_PRAGER » law of behavior with parabolic negative work hardening for a confinement of \(2\mathrm{MPa}\).

  • 3D modeling with HEXA20 meshes.

E modeling:

  • « DRUCK_PRAG_N_A » law of behavior with linear, parabolic and exponential hardening, for a confinement of \(2\mathrm{MPa}\)

  • QUAD4 mesh model AXISavec.

F modeling:

  • « DRUCK_PRAG_N_A » law of behavior with linear, parabolic and exponential hardening, for a confinement of \(2\mathrm{MPa}\)

  • 3D model with HEXA20 meshes.
