2008 Ect Benchmark Results: Modeling with Civa of 3d Flaws Responses in Planar and Cylindrical Work Pieces
The configurations proposed in the 2008 ECT modeling benchmark session are addressed in this paper using the eddy current modeling tool embedded into CIVA, which is a multi-technique simulation platform dedicated to NDT and developed at the French Atomic Energy Commission (CEA). The theoretical approach used in CIVA for ECT modeling is based on Volume integral Method (VIM) coupled with the Method of Moments (MoM) and thus leads to fast and accurate calculations in the case of canonical geometries. Symmetries of the configurations considered in this benchmark are moreover exploited by using the Dodd and Deed formalism for the field computations. After a presentation of the semi-analytical model, results obtained in all benchmark cases are discussed and compared with experimental data.
