CALCULATION METHODS FOR EFFECTIVE CONSTANTS OF PERIODIC COMPOSITE MEDIA

Three calculation methods for the determination of effective constants of composite media are studied in detail. An approximate method for t he definite integral presented here makes the transformation field met hod capable of computing the effective conductivity of composite media with overlapping inclusions. The collocation method is used to calcul ate the effective thermal conductivity of composite media, which illum inates the validity ot the collocation method for composite media with potential discontinuity at phase interfaces.
