2013 eddy current benchmark problem: Solution via a coupled integral approach

Abstract : This work proposes a solution to the 2013 eddy current testing benchmark, published by the WFNDEC. The simulated results have been obtained by employing a newly developed semi-analytical approach, based on the coupled use of the classical Volume Integral Method (VIM) and the Boundary Element Method (BEM). An analytical overview on the coupled VIM-BEM approach is first given, in order to explain its theoretical background. Then, the results obtained are discussed from the points of view of accuracy and efficiency, respectively.
