Abstract
This paper studies method of quantitative crack monitoring based on the in-situ Eddy Current Monitoring (ECM) system. The capability of the ECM system in monitoring fatigue crack propagation is discussed along with the crack growth simulation. The fatigue tests for two austenitic stainless steel specimens were conducted, one has a V-notch and the other has a semi-elliptic slit. Their crack propagation was nonitored by means of eddy current testing (ECT) at room temperature. The numerical simulation of crack propagation by using stress intensity factor and a diagram of fatigue crack propagation velocity was carried out to derive mesh models for ECM signal calculation. Comparisons between experimental and numerical ECM signals reveal that this system is capable of quantitatively monitoring the crack growth process.
