Reflection of a Rayleigh wave from the edge of a wedge in oblique incidence

The reflection of a Rayleigh wave from the edge of a sharp elastic wedge in oblique incidence is aaalyzed. It is shown that the nature of the angular dependence of the modulus of the reflection coeffrcient is strongly affected by the phase shift of the symmetric field mode associated with reflection from a caustic. The results are tested experimentally

Directivity patterns of a spark source of acoustic waves in a solid

The direcrional characteristics of a spark source of acoustic waves in a solid are studied experimentally' The angular dependence of the ampiituJes of longitudinal and shear waves and of Rayleigh surface waves is inuestigated for two principal discharge geometries. A qualitative interpretation of the observed dependences is given
