Acoustic emission from crumpling paper.
From magnetic systems to the crust of the earth, many physical systems that exhibit a multiplicity of metastable states emit pulses with a broad power law distribution in energy. Digital audio recordings reveal that paper being crumpled, which can be easily held in hand, is such a system. Crumpling paper both using the traditional hand method and a cylindrical geometry uncovered a power law dis...
متن کاملAcoustic Emission Applied to Mechanically Loaded Paper
Acoustic Emission applied to mechanically loaded Paper (AEP) is a current European Union funded Fifth Framework project. The overall objective of this project is to investigate the micro mechanics behind the behaviour of paper under mechanical loading, with a view to enabling the development of new and value added paper products with a better competitive edge in the global market. To achieve th...

From magnetic systems to the crust of the earth, many physical systems that exhibit a multiplicity of metastable states emit pulses with a broad power law distribution in energy. Digital audio recordings reveal that paper being crumpled, a system that can be easily held in hand, is such a system. Crumpling paper both using the traditional hand method and a novel cylindrical geometry uncovered a...
متن کاملAcoustic emission from BiSrCaCuO superconducting samples
The aim of the paper was to show if the acoustic emission (AE) signals from BiSrCaCuO ceramic superconductors appear during normal state–superconductivity transition. These AE signals were previously observed from YBaCuOtype superconducting materials. The BiSrCaCuO samples were prepared and characterised. The resistance–temperature and current–voltage characteristics of these samples were measu...
متن کاملAcoustic Emission from a Growing Crack
An analytical method is being developed to determine the signature of an acoustic emission waveform from a growing crack and the results of this analysis are compared to experimentally obtained values. Within the assumptions of linear elastic fracture mechanics, a two dimensional model is developed to examine a semi-infinite crack that, after propagating with a constant velocity, suddenly stops...
