Acoustic emission and released seismic energy [PDF]

Natural Hazards and Earth System Sciences, 2005
Abstract. Intense crises of crustal stress appear to cross large regions, and to precede by several months the eventual occurrence of some strong earthquake within them. The phenomenon is not linear, and the stress control reflects some wide scale-size rather than local effects.

Research of Intelligent Acoustic Emission Instrument

Gong-kuang zidonghua, 2011
In view of problems that current acoustic emission instruments have only collection function of acoustic emission data, but no function of data processing and analysis, the paper proposed a design scheme of an intelligent acoustic emission instrument ...

Acoustic emission during the millisecond laser-optical glass interaction assisted by the nanosecond laser

AIP Advances, 2018
A hydrophone is used to detect the acoustic emission for the combined pulsed laser (CPL)-BK7 glass interaction. The CPL is composed of a nanosecond (ns) laser and a millisecond (ms) laser, which are separated with a certain period of time.

Acoustic emission across the magnetostructural transition of the giant magnetocaloric Gd5Si2Ge2 compound [PDF]

, 2005
We report on the existence of acoustic emission during the paramagnetic-monoclinic to ferromagnetic-orthorhombic magnetostructural phase transition in the giant magnetocaloric Gd5Si2Ge2 compound.

Acoustic Emission from crumpling paper

, 1995
From magnetic systems to the crust of the earth, many physical systems that exibit a multiplicty of metastable states emit pulses with a broad power law distribution in energy.
