Abstract EN
We propose a simple, quick, and cost-effective method for nondestructive eddy-current testing of metallic cables.
Inclusions in the cross section of the cable are detected on the basis of certain global data: hysteresis loop measurements for different frequencies.
We detect air-gap inclusions inside the cross section using a homogenized model.
The problem, which can be understood as an inverse spectral problem, is posed in two dimensions.
We consider its reduction to one dimension.
The identifiability is studied.
We obtain a uniqueness result for a single inclusion in 1D by two measurements for sufficiently low frequency.
We study the sensibility of the inverse problem numerically.
A study case with real data is performed to confirm the usefulness.
