【 摘 要 】

In this vibration analysis, influence of ring supports on functionally gradient threelayeredsandwich cylindrical shells is presented with middle layer fabricated ofisotropic material. The ring support is introduced beside radial direction of the shell.Love’s first order thin shell theory is used for strain- and curvature-displacementsrelationship. Rayleigh–Ritz approach is employed to form the shell frequency equation.Axial modal dependence is approximated by characteristics beam functions. Study iscarried out for placing ring support in different position of the shell, for differentconfiguration of the functionally graded material’s layers to investigate the naturalfrequencies of the cylindrical shells under different boundary conditions for a numberof physical parameters. Results obtained are validated with the previous publishedworks in the open literature.
