  • Abstract
    The relationship between the bulk and surface related sources of acoustic emission (AE) is studied by analysing the effect of geometry and the surface on AE-level. The AE maximum at the onset of plastic deformation is found to be proportional to the surface area. It is concluded that AE during early stages of plastic deformation of both single and polycrystals is largely determined by the surface related defects.
