Abstract: A contact-type line-focus ultrasonic probe that transmits SH wave is newly developed. The probe is composed of a quarter- or half-cylindrical wedge and a piezoelectric transducer attached to the cylindrical surface of the wedge. Cylindrical SH wave is excited from the transducer to the wedge and focuses on a line at the bottom surface of the wedge. Hence SH wave is incident upon the testing object at all angles from zero to 90 degrees simultaneously. The directivity of the probe is examined by a conventional method using a half-cylindrical testing block and compared with that of the longitudinal wave probe developed previously.
