    Abstract

    Acoustic emission (AE) has been recorded for a magnesium alloy that has been quasi-statically cycled elastically between zero load and tension. Delayed AE was observed during both loading and unloading, and the stress delay during unloading is further studied. An analytical expression is written for the AE unloading stress delay which is an elastic constitutive parameter. The potential use of these results for the acoustic emission monitoring of elastic stress states is discussed.
