v6.02.502 SSNL502 - Buckle beam

Summary:

This test represents a calculation of the stability of a console beam subjected to a compression force at one end. It makes it possible to validate finite element models:

• COQUE_3D with TRIA7 and QUAD9 stitches,

• DKT with TRIA3 and QUAD4 stitches,

• DKTGavec the TRIA3et QUAD4 knitwear,

• POU_D_T_GD and POU_D_TGM with SEG2 stitches.

in the non-linear, semi-static domain in large displacements and in large rotations in the presence of instability (Euler buckling).

The movements and the moments obtained are compared to an analytical reference solution.
