Abstract
In this study, the dynamic behavior of shear deformable heterogeneous nanocomposite sandwich cylindri-cal panels containing carbon nanotube (CNT) patterned layers is investigated. The basic differential equa-tions of the sandwich cylindrical panel composed of CNT patterned layers based on the Donnell type shell theory are derived. Then basic equations are solved by applying Galerkin method and obtained expression for the nondimensional free vibration frequency of three-layer nanocomposite cylindrical panels within the first order shear deformation shell theory (FOSDST). Finally, the influences of transverse shear strains, volume fractions, arrangement of sandwich nanocomposite layers on the nondimensional free vibration frequency are studied.
