Moderate large deflection of composite laminated plates with edges elastically restrained against rotation using higher-order shear deformation theory

Geometrically nonlinear governing equations and their boundary conditions of composite laminated plates are obtained in the form of displacements by the virtual displacement principle.They are based on the Reddy's higher-order shear deformation theory.All five-displacement functions satisfy the boundary conditions that all edges are elastically restrained against rotation.Galerkin's method is used to transfer dimensionless governing equations to an infinite set of nonlinear algebraic equations solved by parameter-regulated iterative procedurse.Numerical results are presented in a dimensionless graphical form that relate to the performances of symmetric cross-ply laminated plates subjected to the uniformly distributed loads.The influence of various factors on deflection and moment is studied.
