v3.02.304 SSLP304 - Orthotropic square plate in uniaxial traction outside the orthotropic axes

Summary:

This test represents the static calculation of a square plate, made of orthotropic elastic material, whose orthotropic axes are inclined by 30 degrees with respect to the base edge, subjected to uniaxial traction. It makes it possible to validate the correct consideration of orthotropic elastic materials and the associated change of coordinate system. 4 models are used: C_ PLAN with mesh QUAD8 and TRIA6, in a first coordinate system, C_ PLAN in a second coordinate system, COQUE_3D with meshes QUAD9 and TRIA7, in small movements and COQUE_3D on big trips. The movements and the constraints obtained are compared to an analytical reference solution.

The first two models of this test are the result of the independent validation of version 3 of Code_Aster (linear static batch).
