Acoustic Emission Testing by Christian U. Grosse,Masayasu Ohtsu Pdf

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.

Structural Health Monitoring Damage Detection Systems for Aerospace by Markus G. R. Sause,Elena Jasiūnienė Pdf

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 article/publication is based upon work from COST Action CA18203 (ODIN - http://odin-cost.com/), supported by COST (European Cooperation in Science and Technology).

Acoustic Emission - Research and Applications by Lefteris Tyler Pdf

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.

Acoustic Emission: Probes and Utilization by Sonny Lin Pdf

A variety of information related to acoustic emission has been compiled in this book. Acoustic Emission (AE) is a phenomenon in which elastic or stress waves are produced from speedy, localized change of strain energy in substances. The practical function of AE first emerged in the 1950s, but it is only in the last two decades that the science, technology and applications of AE have progressed notably. At present, AE has become one of the most significant non-destructive testing methods. This multidisciplinary book contains data which demonstrates that the AE method is constantly rising and extensively functional in on-line monitoring of civil-engineering constructions such as flyovers, buildings, etc. AE is also applied for the exposure of fatigue cracks and their positions in complex vessels and pipelines, damage estimation in fiber-toughened polymer-matrix compounds, among others. This book will be helpful for both students and experts interested in this field.
