ACOUSTIC EMISSION UNDER APPLIED STRESS

Abstract

A series of tests were conducted on aluminum single crystals of the so-called 0.5 orientation. The data obtained to date were studied relative to the physical behavior of the 0.5 specimens and also with regard to that previously obtained on (100) specimens. Various characteristics are presented of the emission and the physical parameters. Again, the data shows a very definite correlation between the emission phenomenon and deformation behavior. It is clear from the information obtained up through the present, that the emission is a consequence of, and is produced by, a particular phenomenological characteristic of the deformation prosess. Several observations were undertaken to determine the particular aspect of the deformation process acting as the source of this emission energy. (Author)
