**v6.02.130** SSNL130 — Non-deformable plate on a spring mat
====================================================================

**Summary:**

The objective is to test and validate the possibilities of the AFFE_CARA_ELEM command, option RIGI_PARASOL in :math:`\mathrm{2D}` and in :math:`\mathrm{3D}` and affected by the dis_shock or DIS_CONTACT behavior.

This test case models a plate, considered to be non-deformable, placed on a spring mat.

• The springs are modeled by DIS_T (K_T_D_L), this makes it possible to impose boundary conditions at the ends of the springs that are not linked to the solid.

• Behaviors DIS_CHOCou DIS_CONTACT allow one-sided behavior of the springs, which leaves the possibility of detaching the plate from the spring mat.

The same problem can also be modelled by interface elements with the behavior relationship CZM_ELAS_MIX which then represent a continuous distribution of springs (modeling E).
