This article investigates the nonlinear bending of functionally graded graphene platelet–reinforced composite plate with dielectric permittivity. Three functionally graded graphene platelet distribution patterns are considered in this study. Effective medium theory is adopted to determine tensile modulus and dielectric permittivity while rule of mixture is used to determine Poisson’s ratio of graphene platelet–reinforced composites. Governing equations for nonlinear bending of the functionally graded graphene platelet–reinforced composite plates are established based on Hamilton’s principle within the framework of first-order shear deformation plate theory and von Kármán geometrical nonlinearity. Through differential quadrature method, the governing equations are numerically solved and the nonlinear bending behaviors of the functionally graded graphene platelet–reinforced composite plates are obtained. The influences of functionally graded distribution pattern, graphene platelet volume fraction and the attributes of electrical loadings on the bending behaviors of the plates are comprehensively examined. It is demonstrated that the performances of the functionally graded graphene platelet–reinforced composite plates can be designed and actively tuned through adjusting several parameters, which will be helpful to develop graphene platelet–reinforced smart materials and structures.

The present study is concerned with static and free vibration analyses of laminated functionally graded carbon nanotube reinforced composite rectangular plates on elastic foundation based on nth-order shear deformation theory. Four types of carbon nanotubes distributions along the plate thickness are considered, which include uniformly distributed and three other functionally graded distributions. Governing differential equations are derived by means of Hamilton’s principle. The differential quadrature method is developed to formulate the problem, and rapid convergence is observed in this study. A numerical comparison with available results in the literature is carried out to show the validity of the proposed theory. Furthermore, effects of the carbon nanotubes volume fraction, thickness side ratio, aspect ratio, foundation parameters, different thermal environments, the number of layers, lamination angle, boundary condition, and carbon nanotubes distribution types on the static response of laminated functionally graded carbon nanotube reinforced composite plates are also investigated.

The present study is concerned with vibro-acoustic behavior analyses of laminated functionally graded carbon nanotube reinforced composite plates based on Reddy’s higher order shear deformation theory. Four types of carbon nanotubes distributions along the plate thickness are considered, which include uniformly distributed and three other functionally graded distributions. Governing differential equations are derived by means of Hamilton’s principle. The sound pressure and radiation efficiency are calculated with Rayleigh integral. A numerical comparison with available results in the literature is carried out to show the validity of the present model. Furthermore, effects of the carbon nanotubes volume fraction, different thermal environments, lamination angle and carbon nanotubes distribution types on the structural and acoustic response of laminated functionally graded carbon nanotube reinforced composite plates are also investigated.

This paper presents an analytical approach to postbuckling behaviors of functionally graded multilayer nanocomposite plates reinforced by a low content of graphene platelets (GPLs) using the first order shear deformation theory, stress function and von Karman-type nonlinear kinematics and include the effect of an initial geometric imperfection. The weight fraction of GPL nano fillers is assumed to be constant in each individual GPL-reinforced composite (GPLRC). The modified Halpin-Tsai micromechanics model that takes into account the GPL geometry effect is adopted to estimate the effective Young’s modulus of GPLRC layers. The plate is assumed to resting on Pasternak foundation model and subjected to mechanical and thermal loads. The results show the influences of the GPL distribution pattern, weight fraction, geometry, elastic foundations, mechanical and temperature loads on the postbuckling behaviors of FG multilayer GPLRC plates.
