Book Synopsis Émission acoustique et durabilité des composites by : Nathalie Godin
Download or read book Émission acoustique et durabilité des composites written by Nathalie Godin and published by ISTE Group. This book was released on 2018-04-01 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: L’un des enjeux en contrôle de santé des structures est la détection précoce de l’endommagement avant que ce dernier ne conduise à la ruine. Dans ce contexte, l’émission acoustique est une technique bien adaptée afin de suivre, en temps réel, l’état de santé d’une structure ou des matériaux qui la constituent. En effet, les mécanismes d’endommagement s’accompagnent de libération d’énergie sous forme d’ondes acoustiques. Des capteurs disposés à la surface de structures ou d’éprouvettes de laboratoire permettent d’enregistrer les signaux d’EA. Cet ouvrage est dédié à l’identification de la signature acoustique des différents mécanismes d’endommagement se produisant dans les matériaux composites à matrice organique, mais aussi dans les matériaux composites à matrice céramique. Les apports de cette approche sont présentés, ainsi que les principales difficultés et les limites. Aussi, la prévision de la durée de vie à l’aide de l’EA pour des essais de longues durées est discutée.
Book Synopsis Acoustic Emission Under Applied Stress by : B. H. Schofield
Download or read book Acoustic Emission Under Applied Stress written by B. H. Schofield and published by . This book was released on 1964 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report concerns specific investigation undertaken to assess the role of the surface oxide layer in the generation of acoustic pulses in metals, i.e., acoustic emission. Experiments were conducted on single crystals of aluminum of different crystallographic orientation. The specimens were pulled in tension both in atmosphere and exposed to etchant solutions. Results demonstrated the oxide layer is not itself an emission source and that the emission characteristics are significantly modified as a result of the influence of the oxide on the deformation behavior of the specimens. Specific observations suggest the operative mechanism of emission generation and the importance of the role played by the surface condition in the deformation of metals.

Available in PDF, EPUB and Kindle. Book excerpt: Acoustic emission is a technique that is being used increasingly in the field of structural integrity assessment using fracture mechanics. The dynamic behaviour of defects is extremely important as a small defect that is growing may well be more significant than a larger stable defect. Acoustic emission is the method used to investigate the behaviour of defects under stress. When a structure is subjected to an external stimulus (change in pressure, load, or temperature), localized sources trigger the release of energy, in the form of stress waves, which propagate to the surface and are recorded by sensors. With the right equipment and setup, motions on the order of picometers can be identified. Sources of AE vary from natural events like earthquakes and rock bursts to the initiation and growth of cracks, slip and dislocation movements, melting, twinning, and phase transformations in metals. In composites, matrix cracking and fibre breakage and debonding contribute to acoustic emissions. AEs have also been measured and recorded in polymers, wood, and concrete, among other materials. This book entitled Acoustic Emission - Research and Applications shows that the AE method is constantly and intensively emerging and broadly applied in: on-line monitoring of civil-engineering structures, fatigue cracks detection and location in pressure vessels and pipelines, damage assessment in fibre-reinforced polymer-matrix composites, monitoring welding applications and corrosion processes, bearing condition diagnostics, partial discharge sources detection and location in power transformers and generators, monitoring the drying process of materials, and in otoacoustic emission analysis.

Download or read book Acoustic Emission written by Zinoviy Nazarchuk and published by Springer. This book was released on 2017-01-23 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph analyses in detail the physical aspects of the elastic waves radiation during deformation or fracture of materials. It presents the methodological bases for the practical use of acoustic emission device, and describes the results of theoretical and experimental researches of evaluation of the crack growth resistance of materials, selection of the useful AE signals. The efficiency of this methodology is shown through the diagnostics of various-purpose industrial objects. The authors obtain results of experimental researches with the help of the new methods and facilities.
Book Synopsis Acoustic Emission by : Wojciech Sikorski
Download or read book Acoustic Emission written by Wojciech Sikorski and published by IntechOpen. This book was released on 2013-03-06 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Acoustic emission (AE) is a phenomenon in which elastic or stress waves are emitted from rapid, localized change of strain energy in material. The practical application of the AE first emerged in the 1950's, but only in the last 20 years the science, technology and applications of AE have progressed significantly. Currently AE has become one of the most important non-destructive testing techniques. This interdisciplinary book consists of nine chapters, which is a proof of the fact that the AE method is continuously and intensively developing and widely applied in: on-line monitoring of civil-engineering structures (e.g. highway bridges, skyscrapers, dams etc.), fatigue cracks detection and location in pressure vessels and pipelines, damage assessment in fibre-reinforced polymer-matrix composites, monitoring welding applications and corrosion processes, bearing condition diagnostics, partial discharge sources detection and location in power transformers and generators, monitoring the drying process of materials, quality evaluation of fruits and vegetables and in otoacoustic emission analysis.

Download or read book Magnetoelastic Acoustic Emission written by Valentyn Skalskyi and published by Springer. This book was released on 2024-02-26 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book presents theoretical and experimental studies to establish the relationship between volume jumps of the 90° domain wall in a ferromagnetic material and the magnitude of the half-space surface displacement caused by it. A method of evaluating the influence of the external magnetic field on the stress intensity factor at the tip of the crack-like defects in ferromagnets is discussed. The influence of hydrogen on the generation of magneto-elastic acoustic emission signals of ferromagnets is described. The features of magneto-elastic acoustic emission due to the presence of plastic deformation, structural changes, and volumetric damage in such structural materials are shown.
