Polarization versus Mori-Tanaka approximations for effective conductivity of isotropic composites
Keywords:effective conductivity, isotropic composite material, polarization approximation, Mori-Tanaka approximation
Our polarization approximations for the effective conductivity of isotropic multicomponent materials, constructed recently as approximate solutions to the minimum energy principles, are compared with the widely used Mori-Tanaka approximation, derived as an approximate solution of the field equations. The similarities and differences, advantages and disadvantages of both approaches are analysed with illustrating numerical examples.
