Wisse, C.J. (author), Smeulders, D.M.J. (author), Chao, G. (author), Van Dongen, M.E.H. (author) The classical theory of wave propagation in elastic cylinders is extended to poro-elastic mandrel modes. The classical theory predicts the existence of undamped L modes and damped C, I, and Z modes. These waves also appear in poro-elastic mandrels, but all of them become damped because of viscous effects. The presence of the Biot slow bulk wave...
