The Acoustic Emission (AE) technique uses ad hoc transducers to
detect AE events caused by crack growth in structures under
external loading. This technique is similar to the one employed in
earthquake control, where seismic waves reach the monitoring
stations placed on the surface of the Earth. And although they take
place on different scales, these two phenomena damage in structural
materials and earthquakes in geophysics are very similar. In both
cases a release of elastic energy from sources located inside a
Both earthquakes and AE signals can be seen as critical
phenomena and follow the Guttenberg-Richter frequency-magnitude
relationship under a wide variety of conditions. The number of
earthquakes and AE signals scale as a power-law of the area of the
rupture zone, where fractal scaling is proposed for the spatial and
temporal distributions of earthquakes and AEs. In addition,
earthquakes can be taken as an example of the notion of
self-organized criticality, since this idea describes the
spontaneous organization of the dynamics of a system towards a very
particular state, analogous to the critical point found in
equilibrium phase transitions. It is also pointed out that brittle
failure phenomena, as identified through AE monitoring in concrete,
masonry and rocks, can be considered as critical phenomena.
This volume includes contributions from internationally
recognized experts in the areas of seismicity and acoustic
emission, presented at the Post-Conference Workshop on Acoustic
Emission and Critical Phenomena: From Structural Mechanics to
Geophysics (Catania, Italy, 22 June 2007) during the 6th
International Conference on Fracture Mechanics of Concrete and
Concrete Structures (FraMCoS-6). Acoustic Emission and Critical
Phenomena: From Structural Mechanics to Geophysics is divided into
two parts: Acoustic Emission and Critical Structural States (Part
1), and Seismic Mechanics and Critical Behaviours (Part 2). The
book brings together the state-of-the-art in areas ranging from the
mechanics of materials to geophysics, and outlines the potential of
the AE technique in terms of practical applications
(non-destructive testing and failure evaluation) and theoretical
developments (critical phenomena in complex systems). The book will
proof to be invaluable to civil and geotechnical engineers, and to
researchers working in the areas of mechanics of materials,
geophysics, and nondestructive measurements and testing."
