Application of Lorentz force eddy current testing and eddy current testing on moving nonmagnetic conductors
Lorentz force eddy current testing is a novel nondestructive testing technique which can be applied preferably to the identification of internal defects in non-ferromagnetic moving conductors. This paper describes the comparison of this new technique with well-known eddy current testing. Measurements and numerical simulations have been done for both techniques for artificial subsurface defects ...
متن کاملHigh Frequency Eddy Current Testing
This paper presents a nondestructive, high frequency electromagnetic evaluation method which can be applied for the examination of periodic conductive strips or conductive fibers using the evanescent modes generated in slits or in dielectric insulation between conductive fibers. For the detection of evanescent waves we propose the use of lenses with metamaterials, both conical Swiss roll type a...
متن کاملCharacterization of Eddy-current Testing Inverse Problems Using Adaptative Databases
One of the main challenges in Eddy Current Testing (ECT) is the solution of the inverse problem, i.e., the determination of the defect properties knowing the measured data. To this end, many approaches and mathematical tools have been proposed. The so-called adaptive database-method has recently been developed. Its main idea is to store corresponding input-output data pairs in a database and, b...
متن کاملHigh-Precision Internal Diameter Measurements Using Eddy Current Arrays
Tubular components subjected to extreme pressure and intense wear, requiring highprecision internal-diameter measurements, were investigated. Such measurements are currently carried out using slow mechanical devices and/or costly laboratory equipment. This paper describes the development process of a new measurement tool, capable of +/0.015mm diameter evaluation, using state-of-the-art eddy cur...
متن کاملInverse Problem in Nondestructive Testing Using Arrayed Eddy Current Sensors
A fast crack profile reconstitution model in nondestructive testing is developed using an arrayed eddy current sensor. The inverse problem is based on an iterative solving of the direct problem using genetic algorithms. In the direct problem, assuming a current excitation, the incident field produced by all the coils of the arrayed sensor is obtained by the translation and superposition of the ...
