Summary of results ====================== **Displacement**: regardless of the type of mesh used (TRIA3, QUAD4), and the modeling used, the results obtained are far from the reference solution, a maximum difference of 19% is observed. On the other hand, we see that the 4 models (DKT, DST,, Q4G and COQUE_3D) give the same results. **Constraints**: regardless of the modeling, the results obtained are far from the reference solution. A maximum difference of 30.5% is observed for constraint SIXY and 18.5% for constraint SIXX. As for the trips, the 4 models give essentially the same results.
