| In this paper, we present a method for characterizing flaws in metallic structures with pulsed eddy current non-destructive testing (NDT), In a first step, we explain why we have chosen a deconvolution method based on Conjugate Gradient algorithm (CG), After a description of this method and the way it is used for characterization, a validation is performed by coupling it with a 2D FEM (2 dimensional finite elements method) package. The obtained results are compared with experimental measurements. In the last step, a parametric study on parameters obtained with the impulse response gives an estimation of the dimensions of the flaw. |
