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

P2L-2 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: The physical process of second-harmonic generation by the primary Lamb waves, propagating in layered planar structures with weak interfaces, has been studied in this paper, where it is shown that the finite normal and tangential interfacial stiffnesses will effectively influence the effect of secondharmonic generating by Lamb wave propagation at the modal expansion coefficients of the Double Frequency Lamb Waves (abbr. DFLWs) and at the dispersion relations of Lamb waves.
