...Benoit Lepage This article focuses on the development of a novel method for synthesizing an eddy current sensor using signal-processing techniques based on the linear superposition of multiple parallel acquisition signals. The proposed method will be demonstrated in the context of a cross-wound...

..., an inspection concept for the reliable detection of fatigue cracks and damage on welds of the offshore tower and foundation structures is essential. In the present study, five different eddy current differential sensors were evaluated on cyclically fatigued DY butt welds under tensile load with a focus...

...Suixian Yang; Shuwen Deng If the relationship between electromagnetic parameters and the stress state were characterized by analyzation, it would be helpful to evaluate and classify the flaws in the sample with eddy current thermography (ECT). This paper reported the numerical simulation...

... on the remaining effective radius of a given rod. Long-time decay up to 0.1 s, in the transient response of pulsed eddy current (PEC), was examined as a potential method to quantify general corrosion in ferromagnetic rebar. The transient response of a coaxial solenoidal drive–receive coil pair, oriented parallel...

..., and plate-to-plate gap from multi-frequency eddy current data. The IA was tested over a large range of first layer wall thickness (3.80–4.64 mm), second layer plate resistivity (1.7–174 µΩ cm), second layer wall thickness (1.20–4.85 mm), probe liftoff (2.8–7.9 mm), and plate-to-plate gap (0–13.3 mm...

...P. R. Underhill; T. Rellinger; T. W. Krause; D. Wowk The use of eddy current (EC) arrays to detect damage in sandwich panels, such as disbonding of the carbon fiber reinforced polymer (CFRP) face-sheet to the core, is investigated. It is shown that the array is very sensitive to slight core crush...

... increasingly important to detect the presence of these defects at the earliest stages of development. Eddy current testing (ECT) is a nondestructive inspection (NDI) technique that has been proven quite effective in detection of damage in metallic structures. However, NDI of composite structures has mainly...
