Thin Conducting Sheet (TCS) in non-destructive testing simulations: implementation in Code_Carmel3D and validation

摘要

This paper presents a novel thin conducting sheet (TCS) model. This model is used to replace 3D thin conductive domains in eddy current simulations by an equivalent impedance boundary condition coupling the tangential electromagnetic fields on both sides of the sheet. It has been implemented in A - Φ and T - Ω finite element formulations of Code Carmel3D. This approach is validated by an analytic comparison (spherical shield). In this paper, it is used to model a thin conductive layer deposited on the outside surface of a tube.
