A Perturbation Method for Asymmetric Problems in Eddy Current Testing
A perturbation method is used to solve eddycurrent testing problems for a flaw of arbitrary shape situated in a conducting half-space when the electric conductivities of the flaw and the surrounding medium are nearly the same. A general formula for the change in impedance is obtained. Examples of cylindrical flaws of finite length and spherical flaws are given. Detailed numerical results are gi...
متن کاملA new database generation method combining maximin method and kriging prediction for eddy-current testing
The accurate numerical simulation of the eddycurrent testing (ECT) experiments usually requires large computational efforts. To avoid the time-consuming computations, the idea – which is new in the domain of ECT – of using databases appeared recently. The database consists of well-chosen pairs of input-output samples of a specified ECT experiment. Once it is built, one just has to retrieve the ...
متن کاملCombination of Maximin and Kriging Prediction Methods for Eddy-Current Testing Database Generation
The numerical simulation of eddy-current non-destructive testing methods involves high complexity and expensive computational load. However, one needs to reach reliable solutions for these problems in order to be able, in particular, to solve the related inverse problem. A way to overcome such a difficulty is to propose a “surrogate modelization” of ECT experiments through the generation of a p...
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 کاملEddy 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...
