THE K-METHOD OF DETERMINING THE PATH FUNCTION

Abstract

The flux distribution in the leakage field produced by 48 cracks of varying dimensions in magnetized ferromagnetic materials was determined by substituting an electric current for the magnetic flux and measuring electric potential in the vicinity of analogous flaws. By these anaogous measurements it is shown that the peak flux density cannot be expected to be unique for both the width and depth of a crack but that the flux density is influenced by the specific defect dimensions. The total leakage flux is not unique for a particular crack depth but depends on the crac width as well. (Author)
