Abstract

The magneto-acoustic stress measurement technique has been evaluated by the authors as a means of revealing information on residual and applied stresses in ferromagnetic materials. Past work has included: documentation of the response of carbon steels to various test configurations [1], the effect of grain size and cooling rates in medium carbon alloy steels [2], test results obtained with a railroad rail sample [3], and investigations performed with a prototype device for examining full railroad wheels [4]. Other published papers have sought to provide detailed reviews of the test theory and model behind this technique in light of the accumulated test data [5,6].
