Thermal analysis of Composite Laminated Plates using Higher-order shear deformation theory with Zig-Zag Function

Abstract

In this paper an analytical procedure is developed to investigate the Thermal characteristics of laminated composite plates under thermal loading based on higher-order displacement model with zig-zag function, with out enforcing zero transverse shear stresses on the top and bottom faces of the laminated plates. This function improves slope discontinuities at the interfaces of laminated composite plates. The related functions are obtained using the dynamic version of principle of virtual work or Hamilton’s principle. The solutions are obtained using Navier’s and numerical methods for anti-symmetric cross-ply and angle-ply laminates with a specific type of simply supported boundary conditions SS-1 and SS-2. The Numerical results are presented for anti-symmetric cross-ply and angle-ply laminated plates. All the solutions presented are close agreement with the theory of elasticity and available literature.
