Abstract :
An overview of recent results which provide new directions for acoustic emission (AE) technology during this decade is given. The 1990s will see new quantitative acoustic emission test methods develop as new technology takes advantage of progress in understanding AE practice. New aspects of AE described herein include different theoretical perspectives, accurate source location in anisotropic materials, broadband waveform measurements, and filtering out background noise. Also mentioned are the technologies needed in order to realize the practical contributions this technique can make to society
