Abstract

Acoustic emission (AE) monitoring has been extensively used for characterising failure mechanisms in composite materials. Recently several investigators have used acoustic emission amplitude distribution analysis (AEAD) to distinguish failure mechanism in composite materials. In this procedure the amplitude distribution of an acoustic emission is considered a characteristic of the source of emission. Iosipescu shear tests were conducted on unidirectional and crossply glass fibre epoxy composites, and the AE monitored with a PAC 3000 system during the test. The data acquired during the tests were analysed using post data analysis software provided by PAC.
