摘要：

A theoretical and numerical model is developed for the computation of Eddy Current (EC) signals provided by a differential type probe used for tubing inspection. The main application of interest is to make simulated experiments for studying the perturbations affecting the EC signal such as the variations of the eccentricity and the probe wobble. 3D flaws are introduced by a variation in the local distribution of the conductivity. The forward problem is handled by using a dyadic Green's function approach. Typical impedance plane trajectories obtained with a differential probe are given.
