.. _V3.03.118: **v3.03.118** SSLS118 - Square plate placed under sinusoidal pressure =============================================================================== **Summary:** The case of a monolayer then multilayer square plate is treated, which is simply supported and subjected to sinusoidal pressure. We calculate the displacement in the center, the constraints .. image:: images/Object_1.svg :width: 25 :height: 24 .. _RefImage_Object_1.svg: , .. image:: images/Object_2.svg :width: 25 :height: 24 .. _RefImage_Object_2.svg: , .. image:: images/Object_3.svg :width: 25 :height: 24 .. _RefImage_Object_3.svg: , .. image:: images/Object_4.svg :width: 25 :height: 24 .. _RefImage_Object_4.svg: , .. image:: images/Object_5.svg :width: 25 :height: 24 .. _RefImage_Object_5.svg: at the lower, middle and upper interfaces, the membrane forces .. image:: images/Object_6.svg :width: 25 :height: 24 .. _RefImage_Object_6.svg: , .. image:: images/Object_7.svg :width: 25 :height: 24 .. _RefImage_Object_7.svg: , .. image:: images/Object_8.svg :width: 25 :height: 24 .. _RefImage_Object_8.svg: , the shear forces .. image:: images/Object_9.svg :width: 25 :height: 24 .. _RefImage_Object_9.svg: , .. image:: images/Object_10.svg :width: 25 :height: 24 .. _RefImage_Object_10.svg: And the moments .. image:: images/Object_11.svg :width: 25 :height: 24 .. _RefImage_Object_11.svg: , .. image:: images/Object_12.svg :width: 25 :height: 24 .. _RefImage_Object_12.svg: and .. image:: images/Object_13.svg :width: 25 :height: 24 .. _RefImage_Object_13.svg: . The test includes 14 models: with regard to models A to F, the results obtained are compared for models DKQ, DSQ, DKT, DST, COQUE_3D with triangular cells and COQUE_3D with rectangular cells. G and H models allow the results to be tested in a user frame that is different from the global frame of reference. The I and J models measure the sensitivity of the results to the fineness of the mesh, for configuration DSQ. The K to N models concern the multilayer plate, for models DST and DSQ, in global and user coordinate systems. They make it possible to estimate the distribution of plane and transverse shear stresses inside the plate. The O to R models validate the Q4G element. The S to T models validate the Q4GG modeling. W modeling validates the T3G element. .. 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 Mod_lisation_F Mod_lisation_G Mod_lisation_H Mod_lisation_I Mod_lisation_J Mod_lisation_K Mod_lisation_L Mod_lisation_M Mod_lisation_N Mod_lisation_O Mod_lisation_P Mod_lisation_Q Mod_lisation_R Mod_lisation_S Mod_lisation_T Mod_lisation_U Mod_lisation_V Mod_lisation_W Synth_se_des_r_sultats
