- Abstract
Attention is drawn to the possibility of using transducers of Rayleigh waves as the sources (receivers) of transverse waves for ultrasonic testing of objects with auxiliary protrusions, at which elastic modes are transformed and scattered. The acoustic section was analyzed and the influence of both the curvature of the radius junction of a protrusion and the wave frequency on the parameters of the formed field was experimentally studied. The contribution of the accompanying subsurface transverse mode and the outgoing mode, which is generated by an edge head wave, to this field was revealed. Data on the influence of the angular position of artificial reflectors inside the specimen with a protrusion on the amplitude of reflected transverse waves, whose primary source is a Rayleigh-wave transducer, are presented.
