Abstract
The present work deals with the use of conformal mapping method in order to analysis multiples axisymmetric defects using established transformations models [1] for eddy current problems in non-destructive testing (NDT) systems. The interest of such a transformation is the generation of electromagnetic field for axisymmetric problem from only the field distribution known in simpler 2D(x-y) geometry. The transformation technique is applied to both geometry and electromagnetic field distribution and validated by comparing the predicted results to reference data [4]. Then multiples defects are investigated.
