.. _V3.03.110: **v3.03.110** SSLS110 - Stability of a compressed square plate ================================================================ **Summary:** A homogeneous isotropic linear elastic square plate simply supported on its four sides is subjected to a linear compression force acting on two of its sides. The critical loads leading to the elastic buckling of the plate are calculated. The geometric rigidity matrix used in solving the eigenvalue problem is the one that is due to the initial constraints. * linear elastic mechanics, * buckling of a shell, * interest of the test: calculation of the geometric rigidity matrix of the elements DKT, DKTG and COQUE_3D, * 6 models. .. toctree:: :hidden: self .. toctree:: :maxdepth: 2 :numbered: Probl_me_de_r_f_rence Solution_de_r_f_rence Mod_lisation_A Mod_lisation_B Mod_lisation_C Mod_lisation_D Mod_lisation_E Synth_se_des_r_sultats
