Multiparameter Methods with Pulsed Eddy Currents

, 1987
Multiparameter methods have been used for a number of years to distinguish certain material properties from others that may be varying in the same eddy-current inspection. Usually the measured data are the magnitudes and phases of the eddy currents at several fixed frequencies. Alternatively, the necessary data can be obtained from pulsed eddy currents

Quantitative Detection of Cracks in Steel Using Eddy Current Pulsed Thermography

Sensors, 2018
Small cracks are common defects in steel and often lead to catastrophic accidents in industrial applications. Various nondestructive testing methods have been investigated for crack detection; however, most current methods focus on qualitative crack ...

Investigation on a new inducer of pulsed eddy current thermography

AIP Advances, 2016
In this paper, a new inducer of pulsed eddy current thermography (PECT) is presented. The use of the inducer can help avoid the problem of blocking the infrared (IR) camera’s view in eddy current thermography technique.

Evaluation of Pulse Eddy Current for Autonomous Airborne Inspections

IEEE Sensors Letters
Unmanned Aerial Vehicles (UAVs) integrated with Pulsed Eddy Current (PEC) technologies present a potential solution for Non-Destructive Testing (NDT) in environments where manual inspection is impractical or hazardous. PEC inspections conducted via UAVs facilitate remote structural health monitoring and offer invaluable thickness measurements for ...

Computation accuracies of boundary element method and finite element method in transient eddy current analysis [PDF]

, 1988
The computation accuracies of the boundary-element method (BEM) and finite-element method (FEM) in transient eddy-current problems are compared by using a slot-embedded conductor model and a diffusion model that can be solved theoretically. For computing
