Acoustic Emission from Paper Fracture [PDF]

open access: yesPhysical Review Letters, 2002
We report tensile failure experiments on paper sheets. The acoustic emission energy and the waiting times between acoustic events follow power-law distributions. This remains true while the strain rate is varied by more than two orders of magnitude. The energy statistics has the exponent $ \sim 1.25 \pm 0.10$ and the waiting times the exponent $ \sim

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

open access: yesAIP 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.
