Abstract

In eddy current non-destructive testing, numerical models have been used for a long time to optimize the method. Those models solve Maxwell’s equations and compute the coil impedance. Many 2-D programs have been realized: for axisymmetrical geometries, with axisymmetrical or very small flaws, to model tube sheets of a steam generator or wires; for an E-shape sensor which generates a one dimensional field to scan a plane surface.
