v6.08.121 SSND121 — Validation of non-linear behavior CHOC_ELAS_TRAC

Summary:

We test the response of the nonlinear behavior model CHOC_ELAS_TRAC, formulated on discrete elements for SEG2 cells.

The STAT_NON_LINE operator is used for validation. The response of discrete elements supporting a nonlinear law of behavior under a cyclic loading is analyzed.

The models and discrete elements tested are in \(3D\) with the DIS_T modeling on SEG2 meshes.

This behavior is also validated for dynamic stresses in test case SDND110 [V5.01.110] with operators DYNA_VIBRA and DYNA_NON_LINE.
