Abstract

The axially symmetric vibrations of an isotropic poroelastic cylindrical panel resting on elastic foundations are investigated in the framework of Biot's theory. The effects of the surrounding elastic medium are considered using the spring constant of the Wrinkler type and the shear constant of the Pasternak type. The frequency equation is obtained for both pervious and impervious surfaces. Non dimensional phase velocity is computed as a function of wavenumber. Numerical results are presented graphically.
