The purpose of this test is to check the elements on a nonisotropic plate structure. Transverse shear effects are necessary, but Kirchoff elements must not be used. The reference is the mesh formed of parabolic hexahedron
elements (HE20).

To Perform the Test:
The simply_supported_sandwich_plate_he20.CATAnalysis document presents the complete analysis of this case, computed with a mesh formed of parabolic hexahedron elements (HE20). These results are the reference.
The simply_supported_sandwich_plate_tr6.CATAnalysis document presents a complete analysis on an orthotropic analog plate, computed with a mesh formed of parabolic triangle elements (TR6).
To compute the case with other meshes, proceed as follow:
Open the simply_supported_sandwich_plate_tr6.CATAnalysis document.
In the Advanced Meshing Tools workbench, replace the mesh specifications.
In the Generative Structural Analysis workbench, compute the case.
