Fundamental studies of two basic Vibro-Acoustic Emission (VAE) source categories of impacts and rubbing are summarized. The effects of the main parameters on these sources were modeled. The feasibility of measuring relative levels of energy dissipation at a rubbing source was demonstrated. The evaluation or prediction of wear rates can be performed. Signal detection and analysis methods were developed to allow qualitative VAE measurements to be made in real structures. VAE was successfully demonstrated for the three application areas of defect detection, failure analysis and mechanism investigations.
