摘要
This paper demonstrates the identification of crack depths using signals obtained from eddy current testing (ECT), The identification method is based on finite elements with the pre-computed unflawed database approach and a meshless crack representation technique, and parameter estimation in non-linear problems. Four different cracks are estimated by using laboratory data.
