The present paper deals with the axial symmetric cylindrical waves propagating
through a cylindrical bore in swelling porous elastic medium. The secular equations,
connecting the phase velocity with wave number, radius of bore and other parameters for
empty and liquid filled bore are derived. A particular case of interest has also been deduced.
Numerical computations have been performed and have also been shown graphically to
understand behavior of phase velocity and attenuation coefficient in swelling porous (SP) and
elastic medium (EL).
Keywords: cylindrical bore; phase velocity; attenuation coefficient; secular equation |
