Abstract

The inspection of rust region in steel is important in the petrochemical plant etc. The B-H curve and the conductivity of rust region in steel are different from those of the normal steel. Therefore, the detection of rust region in steel is possible by detecting the difference of those electromagnetic properties using the inspection method. In this paper, those electromagnetic properties of the rust region in steel are measured utilizing 3-D axis-symmetric FEM and experiment. The electromagnetic inspection technique of the rust region is examined using 3-D edge-based hexahedral nonlinear FEM. In addition, the experimental verification is also carried out.
