Download or read book Ultrasonic and Advanced Methods for Nondestructive Testing and Material Characterization written by C. H. Chen and published by World Scientific. This book was released on 2007 with total page 682 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ultrasonic methods have been very popular in nondestructive testing and characterization of materials. This book deals with both industrial ultrasound and medical ultrasound. The advantages of ultrasound include flexibility, low cost, in-line operation, and providing data in both signal and image formats for further analysis. The book devotes 11 chapters to ultrasonic methods. However, ultrasonic methods can be much less effective with some applications. So the book also has 14 chapters catering to other or advanced methods for nondestructive testing or material characterization. Topics like structural health monitoring, Terahertz methods, X-ray and thermography methods are presented. Besides different sensors for nondestructive testing, the book places much emphasis on signal/image processing and pattern recognition of the signals acquired.

Download or read book Le TOFD Time of Flight Diffraction written by Cofrend Cofrend and published by BoD - Books on Demand France. This book was released on 2013-05-10 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: La technique TOFD -"Time of Flight Diffraction" ou "mesure de temps de vol de l'onde diffractée"- est une technique de contrôle non destructif ultrasonore apparue dans les années 70. Contrairement aux techniques ultrasonores conventionnelles, elle est basée principalement sur l’analyse du temps de vol des signaux de diffraction. Ce phénomène de diffraction intervient lorsqu’un faisceau ultrasonore rencontre un obstacle dont chacun des points réémet alors des ondes omnidirectionnelles. Cette technique utilise des critères d’acceptation différents de ceux utilisés en ultrasons conventionnels. Après s’être principalement développée dans les pays anglo-saxons, la technique TOFD voit aujourd’hui son utilisation s’intensifier, notamment grâce à la mise en place très récente d’une normalisation européenne. Dans ces conditions, la COFREND a souhaité mettre à la disposition des industriels un Guide, outil d’information, pouvant les aider à mieux appréhender les conditions d’utilisation et de mise en œuvre de cette technique. La technique TOFD peut être utilisée en tant que technique de contrôle qualité ou expertise aussi bien au stade de la fabrication qu'au stade de l’exploitation (inspection en service, suivi et maintenance). En fabrication la technique TOFD est essentiellement mise en œuvre pour le contrôle des soudures conformément à une méthodologie de détection et de classification des indications définie dans un code de construction ou une norme. En stade exploitation, la technique TOFD est mise en œuvre dans un domaine beaucoup plus large couvrant également la recherche de corrosion. Les défauts recherchés sont du type : - ponctuel ou non dans le volume, - débouchant ou non en surface de sondage ou en paroi opposée, - avec hauteur mesurable ou non. L'analyse opérée sur les indications conduit à effectuer ou non une réparation en fonction de niveaux d’acceptation fixés par le code de construction, la norme ad-hoc, ou des spécifications contractuelles. Elle est confiée à des opérateurs formés spécifiquement à cette technique TOFD qui doivent en connaitre les conditions de mise en œuvre, les performances et les limites.

Available in PDF, EPUB and Kindle. Book excerpt: This extensively revised and updated second edition of a widely read classic presents the use of ultrasound in nondestructive evaluation (NDE) inspections. Retaining the first edition's use of wave propagation /scattering theory and linear system theory, this volume also adds significant new material including: the introduction of MATLAB® functions and scripts that evaluate key results involving beam propagation and scattering, flaw sizing, and the modeling of ultrasonic systems. elements of Gaussian beam theory and a multi-Gaussian ultrasonic beam model for bulk wave transducers. a new chapter on the connection between ultrasonic modeling and probability of detection (POD) and reliability models. new and improved derivations of ultrasonic measurement models. updated coverage of ultrasonic simulators that have been developed around the world. Students, engineers, and researchers working in the ultrasonic NDE field will find a wealth of information on the modeling of ultrasonic inspections and the fundamental ultrasonic experiments that support those models in this new edition.

Available in PDF, EPUB and Kindle. Book excerpt: This book deals with a number of fundamental issues related to the practical implementation of ultrasonic NDT techniques in an industrial environment. The book discusses advanced academic research results and their application to industrial procedures. The text covers the choice and generation of the signals energizing the system to probe position optimization, from quality assessment evaluation to tomographic inversion. With a focus to deepen a number of fundamental aspects involved in the specific objective of designing and developing an ultrasonic imaging system for nondestructive testing, aimed to automatically classify the entire production of an industrial production line, targeted to the field of precision mechanics. The contents of this book is the result of the common effort of six University Research Groups that focused their research activities for two years on this specific objective, working in direct conjunction with primary industrial firms, in a research project funded by the Italian government as a Strategic Research Project.

Download or read book Exploratory Development of Nondestructive Testing Techniques for Diffusion bonded Interfaces written by George Martin and published by . This book was released on 1969 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report covers exploratory development of nondestructive testing techniques for solid-state diffusion-bonded parts. A literature survey describes the current inspection practices employed on diffusion-bonded laminates and the nature of the interface and bond properties. Test specimens of titanium, columbium, and TD-nickel were prepared for evaluating various test methods. The specimens provided a range of thicknesses and varying degree of bond quality as determined by mechanical property tests. In addition, a number of diffusion-bonded specimens were supplied by the Air Force. Conventional ultrasonic techniques and recently developed selective interface inspection techniques clearly indicate bond conditions where these vary from a no-bond condition to substandard bonds. A number of methods show potential correlation between a quantitative expression of bond quality such as shear or tensile strength. These methods include longitudinal and shear wave velocity, ultrasonic attenuation, and vibration analysis. (Author).
