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

Delamination detection in composite laminates using high-frequency P- and S-waves – Part II: Experimental validation
TL;DR: Pasquali and Lacarbonara as discussed by the authors investigated the through-the-thickness propagation direction of composite laminates undergoing delaminations and found a precise correlation between the delamination position and the variations of the Time of Flight (ToF) of primary (P) and secondary (S) waves.

Development of underwater beacon for Arctic through-ice communication via satellite
TL;DR: In this article, an underwater identification (UWID) tag is deployed under the ice at the site of the trapped oil which contains a pseudosonar beacon projecting upwards at a critical angle to the ice in order to preferentially generate Lamb waves in the ice that radiate outwards from the UWID location.

Time-Domain Second-Harmonic Generation of Primary Lamb-Wave Propagation in an Elastic Plate
TL;DR: In this paper, the authors present an experimental observation of the generation of the time-domain second harmonic by propagation of the primary Lamb-wave tone-burst, and show that the duration of the second-harmonic toneburst increases with the increasing propagation distance.

Ultrasonic Waves in Solid Media
TL;DR: In this article, the theory of elasticity was introduced and basic formulas and concepts in complex variables in the theory and application of wave propagation were discussed. But the authors did not consider the effects of wave scattering on the wave propagation experiments.
