Abstract

In this paper, the evaluation of the characteristics of a new type rotating eddy-current probe for nondestructive Eddy-Current Testing (ECT) is carried out using 3-D edge based FEM. The changes of the induced electromotive force are monitored for various inner and outer types of thin cracks inside the metal plate. It was verified that although the intensity of the signal obtained by this new type of probe is smaller than the conventional ones, the shape of the signal and especially its trace be very useful for detection of the shape, direction and depths of thin cracks and flaws inside thin conducting materials.
