| Research Abstract |
A new mathematical approach for the ultrasonic inspection by employing the optimization method has been proposed in order to improve the efficiency of ultrasonic inspection based on the wave propagation visualization technique. The main idea of this study is to focus on two issues, that is, how to select the searching points in inspection and how to determine the route to visit all the searching points. The validity and properties of the new method have been numerically and experimentally investigated by comparing with the conventional one. As a result, it is shown that the efficiency of the ultrasonic inspection is significantly improved by the new method. Moreover, based on the obtained results, some conditions for improving the inspection efficiency are demonstrated, which should be appropriately chosen by inspectors. Finally, the obtained results indicate that the proposed new method in the present study has the advantages in the efficiency of the ultrasonic inspection in practical applications.
