| Abstract: | The recent advances in ultrasonic guided wave testing technique are summarized. Firstly, the disperse characteristics and the related theoretical results of the guided waves in different materials and distinct structures are introduced. Then, based on the structure of the guided waves, the distribution of the energy and displacement of guided waves is analyzed. Lastly, some new techniques of numerical analysis and signal processing for guided wave nondestructive testing are described. |
