Buckling of the Composite Laminates under Mechanical Loads with Different Layups using Different Plate Theories

Abstract

An analytical and numerical solution for general laminated composite plates under mechanical loading is presented based on different lamination plate theories (CLPT and FSDT). General lamination was evaluated by assumption of cross-ply and angle-ply laminated plates. In order to this, Navier-type method and simply supported boundary conditions for rectangular laminates are applied. As a verification method, a finite element code using ANS YS is also developed. Effects of lamination scheme, axial load direction, modulus ratio, plate aspect ratio and lamination angle on critical buckling loads of laminated composite are also investigated and good agreement is found between evaluated results and those available in open literature.
