Abstract

Experimental results on the localization of acoustic emission (AE) signals obtained in stress-cycling tests of specimens made from the Organit-10T composite material (CM) are considered. The technique developed for collecting prompt information on the changes in the shape of the AE amplitude distribution is analyzed. This distribution characterizes the flow of arriving signals and allows one to determine the beginning of destruction for CM specimens.
