摘要

Simple explicit formulas are derived for predicting AE waveforms in finite laminated composite plates excited by an arbitrary source using the normal mode solutions to the extended Mindlin plate theory. The WavePredictor™ software package was developed based on those efficient waveform solutions. The software package allows the user to simulate the AE waveforms in both isotropic and composite laminate finite plates, and can account for the effects of the AE source, edge reflections, material property, sensor aperture, and the acquisition system frequency response.
