Amplitude measurement in acoustic emission
Review of Scientific Instruments, 1985A circuit capable of measuring the amplitude of continuous emission and acoustic bursts is presented. The circuit shows linear behavior (+/−5%) over a dynamic range in excess of 65 dB, for frequencies up to 250 KHz. Possible applications are discussed.

Numerical Calculations of Acoustic Emission
Journal of Nondestructive Evaluation, 1987Two computer programs which solve the partial differential equations for sound propagation numerically are applied to the study of problems in acoustic emission. The programs use finite difference and finite element techniques to calculate sound fields due to distributions of sources in complex geometries in two dimensions. The potential to handle more

The effect of geometry on acoustic emission
1980Acoustic emissions are impulsive elastic waves which are part of the total energy release from many metallurgical phenomena. The emissions signature carry information about the source mechanisms and the present interest of investigators is to identify the acoustic emission sources in terms of material fatigue and fracture parameters in order to ...
