Abstract

An eight-channel data-acquisition system is used to acquire and analyze acoustic-emission (AE) data from aluminum surface-crack specimens. The data acquisition system and an automatic method of analysis are described in a previous paper [1]. In the current paper, a semiautomatic data analysis method for determining the source locations is described, and the results from tests on aluminum specimens are discussed.
