v6.03.124 SSNP124 — Drained biaxial test with DRUCK_PRAGER softening behavior

Summary:

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

Modeling A

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

• model D_ PLAN with QUAD4 meshes.

Modeling B:

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

• model D_ PLAN with QUAD4 meshes.
