Buckling Analysis of Laminated Composite Plates using Layer Wise Higher Order Shear Deformation Theory

This paper represents the investigation on the response of symmetric laminated composite plate. In this paper, an attempt is made to study the Buckling characteristics of a laminated composite plates, using layer wise HSDT. Buckling is one of the major modes of failure of laminated structures and it is necessary to predict the critical load of the structural component, for the easy replacement with good load bearing capacity. Studying buckling characteristics of laminated composite plates is essential, in order to have a deep insight of their behaviour for proper analysis and design. The derivation of equations of motion for layer wise higher order models is obtained, using the virtual work principle. Further, the analytical solutions are developed to find buckling characteristics of laminated composite plates. The solution predicts critical buckling load of laminated composite plate. The results obtained by using the present model are compared with the available literature.
