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: Acoustic Emission (AE) techniques have been studied in civil engineering for a long time. The techniques are recently going to be more and more applied to practical applications and to be standardized in the codes. This is because the increase of aging structures and disastrous damages due to recent earthquakes urgently demand for maintenance and retrofit of civil structures in service for example. It results in the need for the development of advanced and effective inspection techniques. Thus, AE techniques draw a great attention to diagnostic applications and in material testing. The 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.

Download or read book Soundscapes Humans and Their Acoustic Environment written by Brigitte Schulte-Fortkamp and published by Springer Nature. This book was released on 2023-04-24 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: The concept of the “Soundscapes” includes all of the sounds in one’s environment and focuses not only on the sounds itself. Instead, it focuses on the interrelationships between person and activity and place, both in space and time. Soundscape also include influences on the acoustic environment through auditory sensation, its interpretation, and the responses to the acoustic environment in context. The conceptual framework of Soundscape describes the “process of perceiving or experiencing and/or understanding an acoustic environment, highlighting general concepts and their relationships: context, sound sources, acoustic environment, auditory sensation, interpretation of auditory sensation, responses, and outcomes” (International Organization for Standardization, ISO 12913-1:2014 Acoustics Soundscape Part Definition and Conceptual Framework, ISO, Geneva, 2014). With soundscape, one achieves a deeper understanding of acoustic environment and its effects on people. The ISO standard 12931-1 on soundscape provides an important, and rigorous, distinction in the use of “Soundscape.” But, it is recognizable that some individuals, particularly planners, designers, lay persons, and even those primarily interested in management of the acoustic environment through environmental noise control, will find it convenient to use “Soundscape” as a synonym for the physical acoustic environment. When it comes to noise management and urban planning, soundscape research has the potential to promote healthy urban environments by sharing and incorporating the significant knowledge of all concerned parties. Understandably, this shows that the communication with regard to noise management has to be forced to guarantee that the specifics of Soundscapes (i.e., the relevance of perception) are seriously considered alongside the whole. This book will bridge the gap between soundscape theory and practice and therefore it will be different from our earlier publications as “Soundscape and the built environment” (ed. by J. Kang and B. Schulte-Fortkamp CRC Press, Taylor and Francis Group, Boca Raton, Fl 2016) and also from the respective Special Issues on Soundscapes in 2012 in The Journal of the Acoustical Society of America (ed. by B. Schulte-Fortkamp and J. Kang), and also the Special Issue in Acta Acustica 2006 *(ed. by B. Schulte-Fortkamp and D. Dubois), and the E-book on soundscape This volume will be driven by the difficult process of standardization of Soundscape and its evaluation procedures. The main goal of the proposed volume is to present and review the developments in Soundscape, reflecting the standardization procedure and the diverse inputs. the needs in management and planning in urban acoustic environments, the book will also focus on the difficulties, as well as the solutions, in interdisciplinary grounded communication, that is, on the one hand, related to science, but on the other to application, that needs guidance.

Download or read book Structural Health Monitoring of Large Structures Using Acoustic Emission Case Histories written by Kanji Ono and published by MDPI. This book was released on 2020-11-23 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: Acoustic emission (AE) techniques have successfully been used for assuring the structural integrity of large rocket motorcases since 1963, and their uses have expanded to ever larger structures, especially as structural health monitoring (SHM) of large structures has become the most urgent task for engineering communities around the world. The needs for advanced AE monitoring methods are felt keenly by those dealing with aging infrastructures. Many publications have appeared covering various aspects of AE techniques, but documentation of actual applications of AE techniques has been mostly limited to reports of successful results without technical details that allow objective evaluation of the results. There are some exceptions in the literature. In this Special Issue of the Acoustics section of Applied Sciences, we seek contributions covering these exceptions cited here. Here, we seek contributions describing case histories of AE applications to large structures that have achieved the goals of SHM by providing adequate technical information supporting the success stories. Types of structures can include aerospace and geological structures, bridges, buildings, factories, maritime facilities, off-shore structures, etc. Experiences with AE monitoring methods designed and proven for large stru

Download or read book Experimental Acoustic Inversion Methods for Exploration of the Shallow Water Environment written by Andrea Caiti and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, research on acoustic remote sensing of the ocean has evolved considerably, especially in studying complex physical and biological processes in shallow water environments. To review the state of the art, an international workshop was held at Carvoeiro, Portugal, in March 1999, bringing together leading international researchers in the field. In contrast to much of the recent theoretical work, emphasis was placed on the experimental validation of the techniques. This volume, based on presentations at this workshop, summarizes a range of diverse and innovative applications. The invited contributions explore the use of acoustics to measure bottom properties and morphology, as well as to probe buried objects within the sediment. Within the water column, sound is applied to imaging of oceanographic features such as currents and tides or monitoring of marine life. Another key theme is the use of sound to solve geometric inverse problems for precise tracking of undersea vehicles. Audience: This volume should be useful both to the novice seeking an introduction to the field and to advanced researchers interested in the latest developments in acoustic sensing of the ocean environment. The workshop was sponsored by the Fundação para a Ciêcia e a Tecnologia (Portuguese Foundation for Science and Technology).

Download or read book Electromagnetic Acoustic Transducers written by Masahiko Hirao and published by Springer. This book was released on 2016-10-25 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: This second edition provides comprehensive information on electromagnetic acoustic transducers (EMATs), from the theory and physical principles of EMATs to the construction of systems and their applications to scientific and industrial ultrasonic measurements on materials. The original version has been complemented with selected ideas on ultrasonic measurement that have emerged since the first edition was released. The book is divided into four parts: PART I offers a self-contained description of the basic elements of coupling mechanisms along with the practical designing of EMATs for various purposes. Several implementations to compensate for EMATs’ low transfer efficiency are provided, along with useful tips on how to make an EMAT. PART II describes the principle of electromagnetic acoustic resonance (EMAR), which makes the most of EMATs’ contactless nature and is the most successful amplification mechanism for precise measurements of velocity and attenuation. PART III applies EMAR to studying physical acoustics. New measurements have emerged with regard to four major subjects: in situ monitoring of dislocation behavior, determination of anisotropic elastic constants, pointwise elasticity mapping (RUM), and acoustic nonlinearity evolution. PART IV deals with a variety of individual issues encountered in industrial applications, for which the EMATs are believed to be the best solutions. This is proven by a number of field applications.
