Acoustic Emission and Fracture Mechanics Testing of Metals and Composites
Abstract
Acoustic emission testing has found many uses in recent years and new applications are constantly being uncovered. One of the most fruitful areas for application lies in the characterization of microscopic processes of yielding and fracture, and macroscopic processes of slow crack growth and onset of fast crack propagation. This paper has described these processes and emphasized that the total counts and count rate depend on the energy released per event and the density of events per unit of deformation. The models presented herein are first order approximations which await confirmation.
