Abstract
The guided wave is a kind of an ultrasonic wave and is used for the non-destructive test of huge structures, such as a pipeline. When defects exist in the structure, such as a slit and thinning, the propagation behavior of the guided wave is very complicated. Therefore, development of the interpretation of the measured guided wave is necessary in the on-site inspection. The authors have studied the guided wave measurement using PVDF. Then, the combination of the magnetostrictive transducer and the PVDF sensor will be applicable for sophisticated interpretation of the guided wave inspection. In this paper, the guided wave of a test specimen with a defect is measured using the combination, and the results are discussed.
