摘要

A new quasi-three-dimensional (quasi-3D) displacement model considering the effects of fifth-order shear deformation and fourth-order normal deformation is developed for the accurate prediction of displacements, in-plane stresses, and transverse shear stresses in laminated composite and sandwich plates. The present theory involves nine unknowns in the displacement field and satisfies traction-free boundary conditions at top and bottom surfaces of the plate. The governing differential equations and associated boundary conditions are obtained using the principle of virtual work. Analytical solutions are obtained using Navier's solution technique. All the displacements and stresses are obtained for simply supported boundary conditions. Transverse shear stresses of laminated composite and sandwich plates are obtained using equilibrium equations of the theory of elasticity by direct integration method. The numerical results are found in excellent agreement with exact elasticity solutions compared with other higher-order theories available in the literature. Hence, it is concluded that the present theory yields accurate predictions of displacements and stresses in laminated composite and sandwich plates.
