초록
In this paper a numerical analysis method for eddy current testing (ECT) with axisymmetric crack is studied. The finite element method(FEM) is used for electromagnetic solution. In this paper the outer diameter crack of INCONEL 600 tube is modelled and the impedance signal is obtained using the differential probe. The characteristics of the crack depth variation in the signal are analyzed.
