Ultrasonic guided wave inspection is expanding rapidly to many different areas of manufacturing and in-service inspection. The purpose of this paper is to provide a vision of ultrasonic guided wave inspection potential aswe move forward into the new millennium. An increased understanding of the basic physics and wave mechanics associated with guided wave inspection has led to an increase in practical nondestructive evaluation and inspection problems. Some fundamental concepts and a number of different applications that are currently being considered will be presented in the paper along with a brief description of the sensor and software technology that will make ultrasonic guided wave inspection commonplace in the next century.read more

Study of Second-Harmonic Generation of Lamb Waves Propagating in Layered Planar Structures with Weak Interfaces
Mingxi Deng,Ping Wang,Xiafu Lv +2 more
TL;DR: In this paper, the effect of interfacial stiffness on the second-harmonic generation by Lamb wave propagation in layered planar structures with weak interfaces was investigated, and it was found that the normal and tangential interfacial stiffnesses of the weak interfaces can effectively influence the effect on the performance of the second harmonic generation.

Time reversal method for guided wave inspection in pipes
TL;DR: In this paper, the application of the time reversal method in pipe-like structures based on finite element method (FEM) is investigated, and a steel pipe model measuring 70 mm x 3.5 mm is used to analyze the reflection coefficient of the L(0,2) mode with the time reversing process.
