v3.03.504 SSLS504 - Composite square plate made up of 3 layers, subjected to doubly sinusoidal loading

Summary:

This test represents the semi-static calculation of a composite square plate made up of 3 layers, which is simply supported, and subjected to doubly sinusoidal loading. This test case makes it possible to validate the modeling of finite elements DST with the TRIA3 and QUAD4 meshes, with a multi-layer composite material.

The movements and the constraints obtained are compared to a numerical reference solution.
