ABSTRACT:
The invention is a method and apparatus for characterizing residual uniaxial stress in a ferromagnetic test member by distinguishing between residual stresses resulting from positive (tension) forces and negative (compression) forces by using the distinct and known magnetoacoustic (MAC) and a novel magnetoacoustic emission (MAE) measurement circuit means. A switch permits the selective operation of the respective circuit means.
