Summary

THE THERMAL CONDUCTIVITY OF A COMPOSITE MEDIUM CONSISTING OF A CONDUCTING MATRIX AND INSULATING FIBRES IS STUDIED. THE EQUIVALENT TRANSVERSE CONDUCTIVITY OF THE COMPOSITE AS A FUNCTION OF THE FIBRE VOLUME FRACTION IS OF INTEREST. THIS IS OBTAINED IN THE PRESENT WORK BY SUBJECTING AN INHOMOGENEOUS REGION TO BOTH STEADY AND STEADY-PERIODIC TEMPERATURE DIFFERENCES. THE RESULTING SET OF EQUATIONS IS SOLVED BY A FINITE ELEMENT TECHNIQUE. RESULTS SHOW THAT A COMPOSITE MEDIUM CAN BE HOMOGENIZED USING STATICALLY DETERMINED CONDUCTIVITIES, EVEN FOR UNSTEADY PROBLEMS.
