Flexoelectricity and surface effects on coupled electromechanical responses of graphene reinforced functionally graded nanocomposites: A unified size-dependent semi-analytical framework

Owing to inhomogeneous strain and high surface-to-volume ratio in nanostructures, it is imperative account for the flexoelectricity as well surface effect while analyzing size-dependent electromechanical responses of nano-scale piezoelectric materials. In this article, a semi-analytical ‘single-term extended Kantorovich method (EKM)’ ‘Ritz method’ based powerful framework developed investigating static dynamic graphene reinforced functionally graded (FG) nanocomposite plates, respectively. The residual stresses, elastic modulus, direct flexoelectric effects are taken into developing unified governing equations boundary conditions. modified Halpin Tsai model rules mixture implemented predict effective bulk properties. Our results reveal that deflection resonance frequency proposed FG nanoplates significantly influenced due consideration effects. While such outcomes emphasize fact cannot be ignored, these also open up notion on-demand property modulation active control. more apparent lesser thickness, but they diminish plate thickness increases, leading realization quantification behavior. Based on formulation, comprehensive numerical investigation further carried out characterize considering different critical parameters thicknesses, aspect ratios, coefficients, multiples, distribution, weight fraction platelets along with With recent advances manufacturing, current work will provide necessary physical insights modeling multifunctional systems control mechanical properties harvesting energy.
