v1.01.369 ZZZZ369 — Validation of option MASS_MECA for elements MEMBRANE and GRILLE_MEMBRANE

Summary

This dynamic test is part of the validation of elements MEMBRANE and GRILLE_MEMBRANE. A concrete plate (modelled in COQUE) contains two reinforcing layers combined on the middle sheet of the plate. The plate is subjected to a punctual force at its center.

In modeling A, grids are modeled by GRILLE_EXCENTRE elements. This modeling is used as a reference. In B modeling, grids are modeled by MEMBRANE elements. In C modeling, grids are modeled by GRILLE_MEMBRANE elements.

This test aims to validate the options MASS_MECA and MASS_MECA_DIAG of the elements MEMBRANE and GRILLE_MEMBRANE.
