Ultrasonic Guided Waves in Solid Media

Abstract

Ultrasonic guided waves in solid media have become a critically important subject in nondestructive testing and structural health monitoring, as new faster, more sensitive, and more economical ways of looking at materials and structures have become possible. This book will lead to fresh creative ideas for use in new inspection procedures. Although the mathematics is sometimes sophisticated, the book can also be read by managers without detailed understanding of the concepts as it can be read from a 'black box' point of view. Overall, the material presented on wave mechanics - in particular, guided wave mechanics - establishes a framework for the creative data collection and signal processing needed to solve many problems using ultrasonic nondestructive evaluation and structural health monitoring. The book can be used as a reference in ultrasonic nondestructive evaluation by professionals and as a textbook for seniors and graduate students. This work extends the coverage of Rose's earlier book Ultrasonic Waves in Solid Media.

Research on Ultrasonic Testing Methods for Adhesion Quality of Ceramic Coatings

“…The relationship between ‫ܣ‬ ଵ and ‫ܣ‬ can be determined by reflection coefficient and transmission coefficient of acoustic pressure of the water-coating interface, given by J. L. Rose [17]:…”

Air-coupled ultrasonic through-transmission thickness measurements of steel plates

“…Ultrasound is used both as a point measurement technique and for inspection of large areas of structures by means of guided waves [9]. Ultrasound is used in a variety of settings, from laboratory measurements to the hand held inspection devices deployed by workers in the field.…”

Non-destructive evaluation of spiral-welded pipes using flexural guided waves

“…Spiral-welded pipes, which are widely applied in fields such as drainage, architecture as well as oil and gas storage and transportation, are difficult to inspect due to their complex geometry. Ultrasonic guided waves has already been demonstrated by various research work to have great potential and a good prospect in on-line Non-Destructive Evaluation (NDE) and long-term Structural Health Monitoring (SHM) of pipelines of various industries [1,2], due to its various corresponding advantages such as singlepoint excitation, long detection range, high inspection efficiency and 100% cross-section coverage. However, the detection sensitivity for defects in spiral-welded pipes is poor when using axisymmetric guided waves.…”
