ON THE RAYLEIGH WAVE ON A CURVILINEAR BOUNDARY BETWEEN ELASTIC AND FLUID MEDIA

摘要

Along the boundary between elastic and fluid media, the surface Rayleigh wave propagates. The velocity of this wave vro in the case of a plane boundary is less than the velocity of the Rayleigh wave ν_R on a free plane boundary of an elastic medium and less than the velocity vpo in a fluid medium. To investigate the velocity vro in the case of curvilinear boundaries, the propagation of Rayleigh waves under consideration along cylindrical and spherical surfaces is studied. The velocity of the Rayleigh wave depends on the curvature of the wave trajectory and the curvature in the direction perpendicular to the trajectory. Furthermore this velocity depends on the presence or absence of a fluid medium. Bibliography: 5 titles.
