Abstract
In this paper, a non-destructive methodology designed for quantification of residual stresses in magnetic steels is presented. A portable anisotropic magnetoresistance (AMR) sensor has been developed for specimen inspection capable of determining the distribution of magnetic permeability tensor in a contactless manner. Correlating the AMR response with residual stresses, the localized stress tensor has been determined. This method holds significant promise for enhancing the reliability and safety of critical components in various ship-environment applications and beyond.
