| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Investigations of reflection phenomena of the T(0,1) mode guided waves at gradually step-down axisymmetric defects were presented. A theoretical model calculating the reflection coefficients at the axisymmetric defect was introduced and was used for comparison to the experiments. It was confirmed that the frequency dependences of the reflection coefficients for the axisymmetric defects were in excellent agreements with the calculations. An inverse problem for estimating a size of defect using the theoretical model was proposed and evaluated. The experimental results of the estimations agreed very well with actual size of defects measured by the ultrasonic thickness gauge. | |
