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

Wave propagation in one-dimensional waveguides for damage characterization
Annamaria Pau,Fabrizio Vestroni +1 more
TL;DR: In this article, the authors examined the response of a bar to an impulsive force along its axis and pointed out the differences in the damaged bar by exploiting the relationship between the damage parameters and the amplitude and time delay of the reflected and transmitted waves.

Detecting the flaws in prestressing strands using guided waves based on the magnetostrictive effect
TL;DR: In this paper, the use of guided waves based on the magnetostrictive effect to detect the small defect and broken wires in the prestressing strand is described, and the results indicate that the method can be applied to not only detect the defects but also quantify the broken wires.

Zhongqing Su,Lin Ye +1 more
TL;DR: A comprehensive solution to Lamb waves was completed by Mindlin in 1950, followed by considerable detail provided by Gazis in 1958 [4] and Viktorov in 1967 [5] who also first evaluated the dispersive properties of Lamb waves as mentioned in this paper.
