Abstract : Highly conducting thin deposits may blind eddy current probes in non-destructive testing of steam generator tubes and thus should be identified. In this report, various asymptotic models are studied to model the axisymmetric thin conducting layers by effective transmission conditions depending on re-scaling parameter and asymptotic expansion order, so as to avoid the high computational cost in a full model due to those thin layers. We also select the most adapted models for practical configurations via numerical comparisons in a simplified case.
