Analyse des contraintes dans les coques cylindriques en matériau composite

Abstract

In this work, the bending analysis of multilayered plates and shells is presented by utilizing a higher order shear deformation theory (HSDT). The proposed involves five unknowns, and without requiring the shear correction coefficient.The equations of motion are derived by using the virtual works principle. These equations are then solved via Navier-type, closed form solutions. Bending results are found for cylindrical shells and plates for simply supported boundary conditions. Results are presented for thick to thin as well as shallow and deep shells. The computed results are compared with the exact 3D elasticity theory and with several other conventional HSDTs. The proposed HSDT is found to be precise compared to other several existing ones for investigating the static response of isotropic and multilayered composite shell and plate structures.
