Abstract

The application of a rotating field like that of induction machines is proposed for the eddy current testing of conducting cylindrical structures. This method allows for fast tracking of the position and geometrical parameters of cracks. In order to improve the capability to discriminate the depth of buried cracks, a suitable range of frequencies is considered. The measurement data are processed with a hybrid neuro-fuzzy system. Two artificial neural networks are used, one is specialized for surface cracks and the other one for buried cracks. The fuzzy system is used to perform the switching strategy between the two networks.
