Torsional vibrations of poroelastic prolate spheroids

In this paper, propagation of torsional vibrations in poroelastic prolate spheroids is investigated employing Biot's theory. Frequency equations of torsional vibrations are obtained for a poroelastic solid prolate spheroid and thick walled prolate spheroidal shells. Frequency equations are the same for pervious and impervious surfaces. Results of previous investigations are shown as a particular case of the present study.
