The well-established Dodd and Deeds models, that are widely used in eddy current nondestructive evaluation (NDE) and have served the industry for three decades, are being reformulated. Integral expressions for the electromagnetic field and the impedance of the eddy current coil are replaced by serie...
Eddy‐current interaction with an ideal crack. I. The forward problem The impedance of an eddy鈥恈urrent probe changes when the current it induces in an electrical conductor is perturbed by a flaw such as a crack. In predicti... BOWLER,J. R. - 《J.appl.phys》 被引量: 213发表: 1994...

The basic idea is that an induction coil induces eddy currents in conducting materials where the involved resistive losses are used for heating. The remote modulated excitation generates thermal waves that interact with boundaries thereby revealing defects. As a thermography camera monitors the temperatur...
There is a considerably history of using Eddy Current measurements for inspecting metal surfaces. The interpretation of the results, however, has been somewhat subjective. The sensitivity of the Eddy Current measurement to changes in material thickness is easily demonstrated. However, the reconstruction ...
