【 摘 要 】

This paper deals with the effect of elastic foundations on the vibrations of thick- walled hollow poroelastic cylinders. The frequency equations of axially symmetric vibrations and non-axially symmetric vibrations, each for pervious and impervious surface are obtained using the analytical model based on Biot's theory. The plots of frequency versus ratio of thickness to inner radius of composite cylinder for different materials are presented graphically.
