Abstract

The propagation characteristics of SH waves passing from the surface through an isotropic medium were investigated by adjusting the incident and receiving angles of two SH wave transducers. Approximately 70% of the total SH wave energy reached a depth of 2 mm when the incident and receiving angles were 24 and 25°, respectively. This phenomenon can be explained easily if the wave diffraction pattern between the transmitter and the receiver is assumed to take an angular path. SH wave attenuation provides a sensitive probe for determining variations in the hardness of surfaces arising from the accumulation of elastic strain and transformation products.
