v3.03.108 SSLS108 - Helical shell under concentrated loads

Summary:

This linear elasticity test is very severe due to its geometry (left shell). It makes it possible to show the influence of warping on the performance of shell elements.

It includes 8 models to test elements COQUE_3D, DKT,, DST and Q4G for various geometric supports.

The reference values are calculation results provided in the literature, the displacement at a point in the structure is checked.
