Development of Ultrasonic Line-Focus SH-Wave Probe
A line-focus ultrasonic SH-wave probe is developed for possible application to TOFD method. The probe is composed of a quarter- or half-cylindrical wedge and a piezoelectric transducer adhered to the cylindrical surface of the wedge. An SH-wave pulse with cylindrical wave front is generated by the transducer, transmitted to the wedge, and focused on a line at the bottom surface of the wedge. Hence, the SH-wave is incident on the specimen surface at all angles from zero to 90 degrees simultaneously. The directivity of the probe is examined and compared with that of the line-focus P-wave probe developed previously.
