Analytical Investigation of Time Dependent Tensional Loading of Stiffened and Un-Stiffened Composite Laminated Plates

In this work, a suggested analytical solution for dynamic analysis of stiffened and un stiffened composite plates subjected to an-axial dynamic loading is presented. The dynamic analysis for equations of motion are solved by using the modal analysis of forced vibration. The results are the response and stress in x and y-direction for symmetric and antisymmetric, cross-ply and angle-ply, laminated plates subjected to the dynamic axial loading conditions of type. In addition, the results for displacement and stresses are presented showing the effect of plate side-to-thickness ratio, aspect ratio, material orthotropy, the effect of boundary conditions, number of layers of laminated, and lamination scheme and are confirmed with other solutions results. Also results for displacement and stresses of stiffened laminated plates are presented showing the effect of number of stiffeners, high to width of stiffener ratio, high of stiffener, the width of stiffener, and the stiffener properties.
