Abstract
The mechanism of electromagnetically induced acoustic emission (EMAE), a nondestructive testing method, is studied at a microscopic level from the viewpoint of energy. The relationship between the generation condition of EMAE and the drop of flow stress in metals under electrical loading is presented. A general theory which correlates acoustic emission with the electroplastic effect is obtained.
