Flexoelectricity indicates a unique characteristic of insulators and dielectric materials that results in electrical polarization induction response to the non-uniform strain gradient. The impact this property is bolder on microscale nanoscale rather than macroscale. This article conducted derive governing equations motion for flexoelectric-multilayer structure evaluate its vibrational behavior various variable variations. model includes functionally graded (FG) porous core which confined between two flexoelectricity-based face sheets at both sides Vlasov type foundation. To gain equations, new power law material beside Hamilton's principle (HP) modified couple stress theory (MCST) implemented. Capturing effects length scale parameter, different materials, aspect thickness ratios, porosity index, foundation parameter boundary conditions (B.C.s) normalized natural frequency (NNF) such multilayer based novel FG formulation serve as main novelty article. According results, it revealed lateral ratio enhancement causes NNF stiffness reduction model. Furthermore, among all considered B.C.s, simply support (SSSS) clamped (CCCC) refer lowest highest respectively. content recent serves good source provide better understanding high stiffness-to-weight structures

In this research, the free vibration and supersonic flutter analyses of a cylindrical sandwich shell with reinforced honeycomb core (RHC) integrated piezoelectric face sheets are investigated. The is structure enriched fibers carbon nanotubes (CNTs). layers modeled based on Cooper-Naghdi theory continuity conditions between considered. aerodynamic pressure flow using linear piston theory. Hamilton's principle used to derive governing equations. A semi-analytical solution presented including an exact in circumferential direction followed by numerical longitudinal via differential quadrature method (DQM). effects several parameters frequencies, corresponding damping coefficients, critical It concluded that improving stiffness CNTs does not necessarily improve aeroelastic stability shell. results can be design analysis aerospace structures.
