Book Synopsis Ultrasonic Testing of Materials by : Josef Krautkrämer
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.

Book Synopsis Engineering Services to Determine Acceptance Limits of Ultrasonic Transducers for Nondestructive Inspection by : V. Devon Smith
Download or read book Engineering Services to Determine Acceptance Limits of Ultrasonic Transducers for Nondestructive Inspection written by V. Devon Smith and published by . This book was released on 1978 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electrical, ultrasonic, and flaw response performance were characterized for 23 ultrasonic transducers used by the Air Force to inspect aircraft components. Wide variation was noted in the response of these transducers to sample flaws, including a flat-bottom hole, an Elox notch, and two laboratory generated fatigue cracks. Seventeen parameters descriptive of the characteristics of these transducers were defined and correlations between these parameters and the flaw detection performance analyzed. Good correlation between loop sensitivity and ability to detect the sample flaws was shown for each transducer in the set. Other parameters of significance appear to be transducer center frequency, beamwidth spectrum inflection, and beam inflection. Definitions of these parameters are presented. A performance rating based on the significant parameters was developed, and, on the basis of this rating, only two of the 23 transducers were judged to be good and eleven fair. In the case of fatigue cracks the response of individual transducers ranged from signals several times the noise background permitting easy crack detection and a transducer rating of good to no signal which means the crack would not be detected and a transducer rating of poor.

Book Synopsis Ultrasound in Food Processing by : Mar Villamiel
Download or read book Ultrasound in Food Processing written by Mar Villamiel and published by John Wiley & Sons. This book was released on 2017-04-25 with total page 764 pages. Available in PDF, EPUB and Kindle. Book excerpt: Part I: Fundamentals of ultrasound This part will cover the main basic principles of ultrasound generation and propagation and those phenomena related to low and high intensity ultrasound applications. The mechanisms involved in food analysis and process monitoring and in food process intensification will be shown. Part II: Low intensity ultrasound applications Low intensity ultrasound applications have been used for non-destructive food analysis as well as for process monitoring. Ultrasonic techniques, based on velocity, attenuation or frequency spectrum analysis, may be considered as rapid, simple, portable and suitable for on-line measurements. Although industrial applications of low-intensity ultrasound, such as meat carcass evaluation, have been used in the food industry for decades, this section will cover the most novel applications, which could be considered as highly relevant for future application in the food industry. Chapters addressing this issue will be divided into three subsections: (1) food control, (2) process monitoring, (3) new trends. Part III: High intensity ultrasound applications High intensity ultrasound application constitutes a way to intensify many food processes. However, the efficient generation and application of ultrasound is essential to achieving a successful effect. This part of the book will begin with a chapter dealing with the importance of the design of efficient ultrasonic application systems. The medium is essential to achieve efficient transmission, and for that reason the particular challenges of applying ultrasound in different media will be addressed. The next part of this section constitutes an up-to-date vision of the use of high intensity ultrasound in food processes. The chapters will be divided into four sections, according to the medium in which the ultrasound vibration is transmitted from the transducers to the product being treated. Thus, solid, liquid, supercritical and gas media have been used for ultrasound propagation. Previous books addressing ultrasonic applications in food processing have been based on the process itself, so chapters have been divided in mass and heat transport, microbial inactivation, etc. This new book will propose a revolutionary overview of ultrasonic applications based on (in the authors’ opinion) the most relevant factor affecting the efficiency of ultrasound applications: the medium in which ultrasound is propagated. Depending on the medium, ultrasonic phenomena can be completely different, but it also affects the complexity of the ultrasonic generation, propagation and application. In addition, the effect of high intensity ultrasound on major components of food, such as proteins, carbohydrates and lipids will be also covered, since this type of information has not been deeply studied in previous books. Other aspects related to the challenges of food industry to incorporate ultrasound devices will be also considered. This point is also very important since, in the last few years, researchers have made huge efforts to integrate fully automated and efficient ultrasound systems to the food production lines but, in some cases, it was not satisfactory. In this sense, it is necessary to identify and review the main related problems to efficiently produce and transmit ultrasound, scale-up, reduce cost, save energy and guarantee the production of safe, healthy and high added value foods.
Book Synopsis Investigation of a Novel Transducer Design for Ultrasonic Non-destructive Testing of Additively Manufactured Metal Components by : Michael Ryan Costa
Download or read book Investigation of a Novel Transducer Design for Ultrasonic Non-destructive Testing of Additively Manufactured Metal Components written by Michael Ryan Costa and published by . This book was released on 2021 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Additively manufactured (AM) components have seen increased use in industry in recent years. AM is of particular interest in aerospace, where high specific stiffness and strength of structural components is desired. AM helps to achieve this goal by adding the capability of manufacturing highly optimized geometry that is not possible or economic with traditional manufacturing methods. With the new processes associated with AM come new challenges for performing non-destructive testing (NDT), as well as qualifying parts for flight use. There are current gaps in NDT processes and technologies with how they can be applied to AM. Current ultrasound NDT systems are not optimized for AM parts. Ultrasonic transducers are generally too large, or do not have the reach to access small features on parts with complex geometry. This research investigates the use of ultrasonic NDT on AM parts using a novel transducer design with a probe like implement designed to gain access to small features that commercial transducers are currently incapable of accessing. A Langevin type ultrasonic transducer is designed and manufactured. Finite element analysis (FEA) is conducted on complex parts in order to determine the feasibility of inspecting components of high complexity by using guided wave ultrasonic NDT techniques. FEA studies show feasibility regarding using guided waves in the 650 kHz range to detect void type defects in a complex part. Multiphysics simulations are employed to provide insight into transducer behavior. A multiphysics study is used to produce a frequency response plot, which shows general correlation to real-world data from the experimental transducer. The transducer's frequency response in the 50 kHz to 650 kHz domain is characterized, and NDT experiments are conducted using plates and an AM component. Testing of an AM part showed better performance for detecting potential flaws under experimental settings when using prescribed damage indices. Results are compared to the performance of a commercial transducer under the same experimental conditions. Damage indices are developed in order to create a aw detection threshold. The experimental transducer is successfully used in detecting a stiffener within a plate, with calculated damage indices being comparable to a commercial transducer.
