Özet
This article presents an analytical and computational investigation into the damped vibrational behavior of functionally graded sandwich nanoplates (FGSNPs) supported by general viscoelastic foundations (GVFs). The nanoplate is modeled using a refined higher order shear deformation theory, and size-dependent effects are incorporated through a nonlocal elasticity theory (NET). This work presents a novel approach wherein the viscoelastic foundation is composed of two distinct layers, where each layer is defined by specific elastic and damping parameters, providing an adaptable framework for the support conditions typically observed in nanoengineered systems. Governing equations are derived using Hamilton’s principle and solved via Navier’s analytical procedure. The proposed model is verified against available benchmark solutions and subsequently employed in a detailed parametric study to examine the influence of geometric dimensions, material gradation, foundation stiffness, and damping characteristics on the vibrational response. This study enhances the mechanics-based understanding of nanoengineered structures and offers valuable insights for the design of advanced multilayered composites, smart structures, and nanodevices operating under complex support and damping conditions.
