The alternating current field measurement (ACFM) technique has been widely used in the
defect detection of metal structures. However, the identification and reconstruction of defects …

DC magnetization is generally considered to suppress the usual local magnetic permeability
variation and increase the penetration depth for magnetizing-based eddy current testing (MB …

This paper presents a nonconventional excitation method with white noise to detect surface
and subsurface cracks in aluminum plates, and the performance of the method was …

In industry, natural cracks usually exist in complex forms such as adjacent, colony, irregular,
and crossing. Mere magnetic field is inadequate to accurately evaluate the complex cracks …

This paper proposes a method to detect and evaluate surface and subsurface cracks in
aluminum multilayer structures using a planar eddy current testing (ECT) probe and …

Metallic structures of non-ferromagnetic materials such as aluminum alloy, titanium alloy,
etc., are widely used in the engineering field of aviation. Owing to harsh and hostile …

This work describes quasi real time flaw (s) characterization in conductive plate (s) through
the inversion of eddy current testing (ECT) signals using learning by examples (LBE) …

For the advantages of corrosion resistance, high toughness and plasticity, the austenitic
stainless steel is widely used in the petrochemical special equipment and offshore structure …

This article presents a distributed current-source (DCS) model considering the perturbation
of the eddy-current (EC) field and its EC-generated magnetic flux density (MFD) caused by …

Planar array capacitive imaging is an emerging nondestructive testing (NDT) technology
with broad application prospects. The severe ill-posed inverse problem of planar array …
