An Eddy Current Parametric Model For Flaw Characterization

摘要

We propose a forward model, based on a parametric approach for characterizing flaws in steam generator tubes, using eddy current technique. This model does not require any parametrization in the case of axisymmetric configurations. In three-dimensional configurations, a parametric description of the deformation of current loops is needed in order to evalaute the impedance change due to a flaw. Some preliminary results show that this parametric approach is promising.
