Bending and Buckling of FG-GRNC Laminated Plates via Quasi-3D Nonlocal Strain Gradient Theory

To improve the structural stiffness, strength and reduce weight of nanoplate structure, functionally graded (FG) graphene-reinforced nanocomposite (GRNC) laminated plates are exploited in this paper. The bending buckling behaviors FG-GRNC nanoplates investigated by using novel quasi-3D hyperbolic higher order shear deformation plate theory conjunction with modified continuum nonlocal strain gradient theory, which considered both length material scale parameters. model Halpin–Tsai is employed to calculate effective Young’s modulus GRNC along thickness direction, Poisson’s ratio mass density computed rule mixture. An analytical approach Galerkin method developed solve governing equilibrium equations obtain closed-form solutions for deflection, stress distributions critical loads. A detailed parametric analysis carried out highlight influences parameter (nonlocal), (gradient), distribution pattern, GPL fraction, stretching, geometry size GPLs, total number layers on stresses, Some details studied exclusively first time, such as stresses nonlocality effect.
