Acoustic Emission and Critical Phenomena [PDF ebook] 
From Structural Mechanics to Geophysics

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, the
