Abstract

Effects of embedded Shape Memory Alloys (SMA) on FREE VIBRATIONs of sandwich-composite panels with a flexible core are investigated. Embedded SMA Wires, according to the characteristics of these alloys, can be effective on frequency and vibration’s behavior of these structures. At this study, the SMA wires (NiTiNol) are symmetrically embedded at mid-plan of top and bottom faces which is composite multilayer. For investigation of the effects of various parameters of this wires on natural frequency and shape mode, at the face plates the first order shear deformation theory (FSDT) and for flexible midcore the Improved high-order theory of sandwich plates (IHSPT) are used so that inertia effects of middle core and face plates are fully considered. Equations for simple boundary conditions, is obtained analytically using Hamilton's principle. Recovery stresses generated by the excitation of built-in SMA wires, is assumed as the work of external forces. Result partial differential equations (PDE) by applying the Galerkin method simple and dissolved.
