    Abstract

    This paper presents selected examples of the acoustic emission response from widely differing materials with varied mechanical history, heat treatment, and state of stress. It presents the case that there is a need for characterization of the acoustic emission response of materials prior to application of the techniques for determining structural integrity so that all parameters are represented under similar conditions.
