摘要：
In this paper, the influence is examined of the apex angle on the velocity of the acoustic edge waves propagating in free linear elastic wedges. The guided antisymmetric waves (ASF modes) are generated and detected with a technique which uses two shear transducers, the directions of polarization of which are perpendicular to the bisecting plane of the wedge. This method, suggested by Pajewski, is analysed and discussed. The experimental measurements of the variation of the free edge wave velocity with respect to the apex angle reveal a very good agreement with the theoretical computations.
