Download or read book The Development of a 2D Ultrasonic Array Inspection for Single Crystal Turbine Blades written by Christopher Lane and published by Springer Science & Business Media. This book was released on 2013-10-30 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis describes the development of a new technique to solve an important industrial inspection requirement for a high-value jet-engine component. The work – and the story told in the thesis – stretches all the way from the fundamentals of wave propagation in anisotropic material and ultrasonic array imaging through to device production and site trials. The book includes a description of a new method to determine crystallographic orientation from 2D ultrasonic array data. Another new method is described that enables volumetric images of an anisotropic material to be generated from 2D ultrasonic array data, based on measured crystallographic orientation. After extensive modeling, a suitable 2D array and deployment fixtures were manufactured and tested on in situ turbine blades in real engines. The final site trial indicated an order of magnitude improvement over the best existing technique in the detectability of a certain type of root cracking. The Development of a 2D Ultrasonic Array Inspection for Single Crystal Turbine Blades should be an inspiration for those starting out on doctoral degrees as it shows the complete development cycle from basic science to industrial usage.

Available in PDF, EPUB and Kindle. Book excerpt: Focusing on the theory and state-of-the-art technologies of ultrasonic testing (UT), this book examines ultrasonic propagation in solids and its detection applications, and explores the intersection of UT technology with various fields of electromagnetics, optics and physics. UT is one of the most widely used nondestructive testing techniques due to its high performance in terms of detection efficiency and safety. The rapid development of modern industrial products and technologies has created a new challenge and demand for ultrasonic nondestructive testing technology. This book introduces the fundamentals of UT, including sound wave and sound field, interface wave theory and liquid-solid coupled sound field. It then discusses various types of UT methods, ranging from the critically refracted longitudinal wave method to ultrasonic surface wave and ultrasonic guided wave detection methods. Some newly developed UT techniques are also discussed, including phased-array UT, high-frequency UT and non-contact UT. This title will appeal to engineering students and technicians in the field of ultrasonic nondestructive testing.

Download or read book Ultrasonic Testing of Materials written by Josef Krautkrämer and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 678 pages. Available in PDF, EPUB and Kindle. Book excerpt: The amendments of this third English edition with respect to the second one concern beside some printing errors the replacement of some pictures in part D by more modern ones and updating the list of stand ards to the state of the fourth German edition. J OSEF KRAUTKRÄMER Cologne, January 1983 Preface to the Second Edition This seeond English edition is based on the third German edition. In view of most recent teehnologieal advanees it has beeome neeessary in many instanees to supplement the seeond German edition and to revise some parts completely. In addition to piezo-eleetric methods, others are now also extensively diseussed in Chapter 8. As for the intensity method, ultrasonie holo graphy is treated in the new Seetion 9. 4. In Part B, for reasons of syste maties, the resonanee method has been ineluded under transit-time methods. It appeared neeessary to elaborate in greater detail the defini tion of the properties of pulse-echo testing equipment and their measure ments (10. 4). The more recent findings of pulse speetroscopy (5. 6) and sound-emission analysis (12) are mentioned only in passing because their significanee is still controversial. Apart from numerous additions, partieularly those coneerning automatie testing installations, Part C also eontains a new chapter whieh deals with tests on nu eIe ar reactors (28), as weIl as abrief diseussion of surfaee-hardness tests (32. 4). It beeame impossible to include a critieal analysis of the principal standards in Chapter 33.

Download or read book Ultrasonic Guided Waves in Solid Media written by Joseph L. Rose and published by Cambridge University Press. This book was released on 2014-08-11 with total page 551 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Geometry of Crystals Polycrystals and Phase Transformations written by Harshad K. D. H. Bhadeshia and published by CRC Press. This book was released on 2017-09-05 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: Organized into a two-part structure aimed at readers of differing experience levels, Geometry of Crystals, Polycrystals, and Phase Transformations is accessible to both newcomers and advanced researchers within the field of crystallography. The first part of the text covers what any reader in the material sciences, physics, chemistry, earth sciences and natural sciences in general should know about crystallography. It is intentionally concise and covers sufficient material to form a firm foundation. The second part is aimed at researchers and discusses phase transformations, deformations, and interface crystallography in depth. The phase transformations are limited to those dominated by crystallography. The entire book contains worked examples and uniquely deals not just with crystals but aggregates of crystals and solid-state transformations between crystals.
Download or read book Handbook of Nondestructive Evaluation 4 0 written by Norbert Meyendorf and published by Springer. This book was released on 2022-03-09 with total page 1263 pages. Available in PDF, EPUB and Kindle. Book excerpt: This handbook comprehensively covers the cutting-edge trends and techniques essential for the integration of nondestructive evaluation (NDE) into the changing face of the modern industrial landscape. In particular, it delves into the marriage of NDE with new techniques in e.g. data mining, cloud computing and autonomous operation, highlighting the potential for cyber-physical controlled production and discussing the myriad possible applications across many different industries. The Handbook of NDE 4.0 centers around the Internet of Things and Industry 4.0 – the next generation of industrial production encompassing all aspects of networking across all industrial areas. It discusses the adaptation of existing NDE techniques to emerging new technological areas, such as 3D printing, via the introduction of cyber systems into the inspection and maintenance processes. In addition, the handbook covers topics such as the management and processing of big data with respect to real-time monitoring of structural integrity and reliable inspection of individual components. Remote NDE to include competence not available on-site will be a potential technique to increase reliability of NDE inspections by integrating additional specialist inputs into the decision process by methods such as telepresence, thereby better leveraging the scarce resources of senior inspectors into industrial inspections at multiple sites. The handbook houses a wealth of essential information to help academics, industry professionals and entrepreneurs navigate through this burgeoning new field. The material in this handbook is presented with the intention of ultimately improving human safety through reliable inspections and dependable maintenance of critical infrastructure, while also enhancing business value through reduced downtime, affordable maintenance, and talent optimization.
