Abstract

On the basis of the background that most studies for quasi-static, low-frequency electromagnetic nondestructive methods consider artificial notches that are, in reality, not always similar to real cracks such as stress corrosion and fatigue cracks, this paper introduces original eddy current inspection data in order to make it available to other researchers in the field. The authors expect this data to be helpful to those who are interested in the application of quasi-static low-frequency electromagnetic field simulations to practical eddy current testing problems. Stress corrosion and fatigue cracks are fabricated into nickel-chromium alloy plates, and eddy current inspections of the plates are performed using four eddy current probes. Signals of four specimens with stress corrosion cracking and another four with fatigue cracks are presented together with profiles of the cracks revealed through destructive testing.
