Abstract :
3D FEM shell elements are used to determine the sensor impedance variation due to ferromagnetic anisotropic metal fibre composites (FAMFC). The homogenization of the FAMFC is realized by the inverse method. The impedance variation gives the information about the lift-off and/or the FAMFC integrity
