Axisymmetric bending analysis of graphene platelet (GPL) sandwich annular and circular nanoplates with FG porous core and integrated with sensor and actuator resting on an elastic substrate under various boundary conditions is presented in this article. The present nanocomposite model is subjected to mechanical load and an external voltage. The upper and lower sandwich layers are made of aluminum matrix with GPL reinforcement. The effective material properties of the sandwich face layers are estimated in the framework of Halpin–Tsai scheme. In accordance with a refined four-variable theory considering the transverse shear and normal strains, the motion equations are obtained from principle of the virtual work. The size effects are considered by employing the nonlocal strain gradient theory. The differential quadrature method is utilized here to solve the governing equations. First, the obtained results are validated by implementing some comparisons with previous work. Then a comprehensive illustration is executed to show the impacts of boundary conditions, GPLs weight fraction, geometrical dimensions, elastic foundation parameters and applied voltage on the bending of the sandwich nanoplates with FG-porous core and piezoelectric layers.
