Eddy Current Tomography for Nondestructive Testing
The paper presents an eddy current tomography setup with high spatial resolution and high accuracy of measurements of signal on detection coil. In proposed solution both amplitude as well as phase shift are measured, which gives the possibility of calculation of spatial distribution of both permeability and resistivity of tested element. As a result, presented setup creates possibility of effec...
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 ...
متن کاملNondestructive testing based on Eddy current method for hybrid electromagnetic shielding systems
Quality rating for hybrid electromagnetic shielding systems is very important in many industrial processes. In fact, the presence of a defect in the final product may occur even if the industry was properly designed and controlled, thus giving rise to unacceptable risks and high costs. Therefore, it is necessary to completely nondestructive inspection of the material during the manufacturing pr...
متن کاملArray Pulsed Eddy Current Imaging Technique for Nondestructive Testing of Aging Aircraft
It is different to detect defect in multilayer structure of an aging aircraft fuselage, pulsed eddy current (PEC) technique has been demonstrated to be capable of quantifying this defect. Based on theoretical analysis of PEC technique, the array probe is designed and the array PEC imaging technique has been supposed to detect corrosion in the multilayer structure. By selecting peak amplitude an...
متن کاملDynamic Piezoresistivity Calibration for Eddy Current Nondestructive Residual Stress Measurements
It has been recently demonstrated [M. P. Blodgett and P. B. Nagy, J. Nondestruct. Eval. 23, 107 (2004)] that eddy current conductivity measurements can be exploited for near-surface residual stress assessment in surface-treated nickel-base superalloy components. To quantitatively assess the prevailing residual stress from eddy current conductivity measurements, the piezoresistivity coefficients...
