Tilt-shift eddy current probe impact on information value of response signal

Tilt-shift eddy current probe impact on information value of response signal Abstract This article deals with the possibility for increasing of the informational value of a response signal using tilt-shift eddy current probe. Numerical simulations based on the FEM method using the OPERA 3D software as well as gained experimental results are presented. The simulated cracks are evaluated at the selected eddy current probe tilts and shifts with respect to conductive plate to obtain additional data needed for its evaluation and localization. Obtained simulation results are compared and discussed with the experimental results. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Archives of Electrical Engineering de Gruyter

Introduction Usability and suitability of products may be limited by the presence of material defects and inhomogeneities arising from their use or incurred in the production. For optimal function of products is required to find these defects to avoid undesirable consequences. To an examination of material defects are often used the electromagnetic nondestructive testing (NDT) and nondestructive evaluation (NDE) methods. The main purpose of these methods is detection of a material inhomogeneities, defects and discontinuities, without mechanical damage of a tested object. Non-destructive evaluation extends this purpose. The maintenance in industry requires expect localization also characterization of a detected defect. The NDE has the ambition to classify and quantify defects that can be detected in various structures, [1, 2]. The main aim of non-destructive methods is to prevent a failure of the components, devices and equipment in industry, medicine, construction or household. The characteristics and advantages of non-destructive methods offer a possibility of periodic and thorough inspection of industry products, which ensures their safe, effective and long-term operation. Eddy current testing (ECT) method belongs to the non-destructive methods and can be applied to conductive materials [3-5]. The ECT is based on the phenomenon of...

Abstract

Abstract This article deals with the possibility for increasing of the informational value of a response signal using tilt-shift eddy current probe. Numerical simulations based on the FEM method using the OPERA 3D software as well as gained experimental results are presented. The simulated cracks are evaluated at the selected eddy current probe tilts and shifts with respect to conductive plate to obtain additional data needed for its evaluation and localization. Obtained simulation results are compared and discussed with the experimental results.
