Abstract :
The 3-D shell elements model is used to determine the sensor impedance variation due to anisotropic metal fiber composite materials (AMFCM). The homogenization of these materials is realized by the inverse problem method. The impedance variation gives the information about the lift off and/or the integrity of the AMFCM
