Abstract

Correlation analysis techniques have been used to characterize acoustic emission pulses from metals. A brief description of correlation functions and the method of their determination is presented. The time varying spectra of a magnesium sample have been obtained using the present techniques, and then compared with the more common methods of measuring acoustic emission. Other uses of correlation analysis in acoustic emission studies are included.
