Available in PDF, EPUB and Kindle. Book excerpt: The book presents topical theoretical and experimental studies for developing advanced methods of detecting materials fracture and assessing their structural state using acoustic emission. It introduces new mathematical models characterizing the displacement fields arising from crack-like defects and establishes a new criterion for classifying different types of materials fracture based on specific parameters obtained from wavelet transforms of acoustic emission signals. The book applies this approach to experimental studies in three types of materials—fiber-reinforced composites, dental materials, and hydrogen-embrittled steels.

Available in PDF, EPUB and Kindle. Book excerpt: SOME STRIKING CHARACTERISTICS HAVE BEEN OBSERVED IN THE FREQUENCY CONTENT OF ACOUSTIC EMISSIONS PRODUCED DURING THE DEFORMATION AND CRACK PROPAGATION IN A533-B PRESSURE VESSEL STEEL, IN CONTRAST TO THE FREQUENCY CONTENT OF ACOUSTIC EMISSIONS PRODUCED DURING TESTS ON 2024 AND 7075 ALUMINUM, 9% NI-4%-CO STEEL, AND 6% AL-4%V TITANIUM. SPECTRUM ANALYSIS OF INDIVIDUAL ACOUSTIC EMISSION BURSTS OVER THE 20 KHZ TO 2 MHZ FREQUENCY RANGE SHOW TWO DISTINCT TYPES OF SPECTRA, ONE OF WHICH CAN BE ASSOCIATED WITH PLASTIC FLOW AND THE OTHER WITH CRACK EXTENSION. ACOUSTIC EMISSIONS ASSOCIATED WITH PLASTIC FLOW ARE CHARACTERIZED BY A BROAD PEAK IN THEIR FREQUENCY SPECTRA AROUND 1 MHZ, AND THOSE ASSOCIATED WITH CRACK GROWTH ARE CHARACTERIZED BY HAVING FREQUENCY COMPONENTS PREDOMINANTLY BELOW 200 KHZ. IT WAS FOUND THAT THESE TWO SPECTRAL TYPES WERE INDEPENDENT OF THE TEST PROCEDURES AND SAMPLE GEOMETRICS USED.

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.

Download or read book Structural Health Monitoring Damage Detection Systems for Aerospace written by Markus G. R. Sause and published by Springer Nature. This book was released on 2021 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book presents established methods of structural health monitoring (SHM) and discusses their technological merit in the current aerospace environment. While the aerospace industry aims for weight reduction to improve fuel efficiency, reduce environmental impact, and to decrease maintenance time and operating costs, aircraft structures are often designed and built heavier than required in order to accommodate unpredictable failure. A way to overcome this approach is the use of SHM systems to detect the presence of defects. This book covers all major contemporary aerospace-relevant SHM methods, from the basics of each method to the various defect types that SHM is required to detect to discussion of signal processing developments alongside considerations of aerospace safety requirements. It will be of interest to professionals in industry and academic researchers alike, as well as engineering students.

This book was released on 1975 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Acoustic emission was monitored during plastic deformation under dead-weight tensile loading of polycrystalline aluminum, brass, copper, and steel. The acoustic emission data, both threshold-type and frequency-analysis type, were correlated with yield strength, stored elastic energy, strain hardening parameters, loading histories, diffusion processes, slip band motion and mosaic cell size. Major results are presented under the headings discontinuous yielding (Portevin--Le Chatelier Effect), parabolic strain hardening, and frequency analysis. The principal experimental techniques are also summarized. (auth).

Available in PDF, EPUB and Kindle. Book excerpt: This book provides an introduction to Acoustic Emission Testing and its applications to different materials like concrete, steel, ceramics, geotechnical materials, polymers, biological structures and wood. Acoustic Emission Techniques (AET) techniques have been studied in engineering for a long time. The techniques are applied more and more to practical investigations and are more and more standardized in codes. This is because the degradation of structures due to ageing urgently demand for maintenance and rehabilitation of structures in service. It results in the need for the development of advanced and efficient inspection techniques. In mechanical engineering and concerning the monitoring of machines and mechanical components, AE is a widely accepted observing deterioration in the frame of structural health monitoring. The advantages of AE like sensitivity, damage localization potential, non-intrusive nature as well as developments in signal analysis and data transmission allow applications that could not be considered decades ago. As such, AE techniques draw great attention to diagnostic applications and in material testing. This book covers all levels from the description of AE basics for AE beginners (level of a student) to sophisticated AE algorithms and applications to real large-scale structures as well as the observation of the cracking process in laboratory specimen to study fracture processes. This book has proved its worth over the past twelve years. Now in its second edition, it will be a resource that sets the standard and equips readers for the future. All chapters from the 1st edition have been updated and rewritten and eight extra chapters (e.g also regarding AE tomography, AE in plate-like structures and AE for investigations of hardening of fresh concrete) have been added.

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.
