Pulsed eddy current (PEC) non-destructive testing and evaluation (NDT&E) has been
around for some time and it is still attracting extensive attention from researchers around the …

Pulsed eddy current (PEC) responses would intersect at a point for a nonferrous plate when
only liftoff distance is varied. In this paper, the behaviors of liftoff point of intersection (LOI) …

Errors in the measurements of pipeline nondestructive tools may lead to faulty decisions
causing economic and environmental loss, or system failures. Calibration models are an …

The degradation of systems in service, including pipelines, over time highlights the critical
need for reliable and accurate defect detection to ensure safe operations. However, single …

Applying contemporary data fusion techniques, the multi-modal nondestructive testing (NDT)
data sets can be combined to obtain more reliable results. The reliability can be quantified in …

Flaw profile characterization from nondestructive evaluation (NDE) measurements is a
typical inverse problem. A novel transformation of this inverse problem into a tracking …

Stress measurement and its variation are key problems in the operating performance of
materials. Stress can affect the material properties and the life of components. There are …

This study proposes an approach to gain information about the depth of near-side flaws
using eddy currents. The approach utilizes only two coils, one of which works as an exciter …

Purpose The purpose of this paper is to propose an approach, which is easy to implement,
for estimating the thickness of the air layer that may separate metallic parts in some …

The identification of structural flaws and subsequent management is significant for health
monitoring of aviation structures. Wall thickness loss can occur because of corrosion in …
