Description

ABSTRACT OF THE DISCLOSURE The present invention provides a method for determining biaxial stresses in a steel component by first generating a calibration datum from an experimental test piece having metallurgical properties similar to steel component and then applying values representative of measured Barkhausen noise levels obtained from the steel component to the calibration datum. The practice of the present invention yields values of strain in the first and second principal directions at the selected location on the steel component under examination.
