| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Corroded part of steel plates buried in concrete is difficult to inspect using visual testing method. Ultrasonic testing method can be expected to have potential for such inspection. In addition to the detection of the presence or absence of corroded part, quantitative detection of residual thickness of steel plates is also desired. In this paper, an ultrasonic testing method for the above purposes is presented. The SH plate wave is transmitted in a steel plate by a SH array transducer, and a received echo by the reflection occurred due to the cut off phenomena of the plate wave is used. Furthermore, configuration of the SH array transducer suitable for the method is studied. It is shown that not only the sensitivity itself but also sensitivity variation among array elements can be improved by ditching grooves on the surface of a protection plate of the transducer that provide stress concentration points on the surface. | |
