摘要
Bulk waves in axisymmetrical poroelastic layers having a given slowness in a plane perpendicular to the symmetry axis of the medium have been previously studied. The previous works are generalized to any angle between the plane where the slowness is defined and the symmetry axis. This allows a description of the Rayleigh waves created by a line source on free surfaces which are not perpendicular to the symmetry axis. An illustration is provided with measurements on a glass wool of the speed of the Rayleigh wave performed in three perpendicular directions and the evaluation of the rigidity parameters of the fibrous medium.
