摘要
A study on the characterization of small cracks by using eddy current testing (ECT) signal is presented. The significant parameters of the ECT data are selected using principal component analysis according to two approaches. The ECT signal inversion is then achieved using a parametric model trained with synthetic data obtained with a fast numerical simulation tool. The characterization procedure is then tested using experimental data. Results show that information can be obtained concerning the area of the cracks.
