چکیده انگلیسی
Quantitative measurements of the amplitude and angular variation of acoustic emission (AE) events due to matrix cracking and delamination in large quasi-isotropic composite plate specimens are reported. A procedure for determining the minimum specimen size necessary to make quantitative measurements is presented. The amplitude of AE events is quoted as the absolute surface displacement of different guided wave modes and can therefore be used as the input to forward models of the AE process. Matrix cracking events are found to be dominated by the S0 guided wave mode and have a pronounced amplitude variation with angle. Events due to delamination growth are dominated by the A0 guided wave mode and have no clear angular dependence.
