TLDR
In this paper, the effect of stress on the magnitude of acoustic emission during magnetization of mild steel and nickel has been investigated, and it has been shown that the acoustic emission shows a strong dependence on stress.Abstract:
The effect of stress on the magnitude of acoustic emission during magnetization of mild steel and nickel has been investigated. It has become clear that the magnitude of acoustic emission during magnetization shows a strong dependence on stress. This effect should have nondestructive testing applications suited for field inspection.read more

Relationship between Acoustic Emission and Dislocation Kinetics in Crystalline Solids
TL;DR: In this article, sounds emitted from single crystals of irradiated LiF, annealed LiF and NaCl during constant-strain-rate compressive deformation were recorded and analyzed, and it was suggested that some 105−106 segments of dislocation line were involved in a cumulative fashion due to the stimulating effect of the moving acoustic wave on bowed dislocation segments.

Acoustic Emission from Single Crystals of LiF and KCl
TL;DR: In this article, an expression for the probability of observing N acoustic emission bursts while the crystal is being strained from e to e+de is written in terms of inverse loop length and used to calculate average values of e, ρM, and (A1/A2), the dislocation strain, mobile d...
