Abstract :
This paper presents an electrical conductivity identification technique of composite materials based on electrical resistance measurement with a frequency range from 1 kHz to 1 MHz. Resistance is measured by an impedance analyzer and also computed using the 3-D anisotropic shell element model. The inverse problem technique is then applied to identify the conductivity tensor components. This technique is validated using anisotropic materials with known electrical conductivity tensor.
