When N = 1, it follows from (3.2) and (3.11) that the result first derived by Maxwell [3] for the analogous case of electrical conductivity is obtained, which may be expressed in the form of a mixtures estimate plus a correction term so that

It follows from (3.28), (3.29) and (3.47) derived using Maxwell’s methodology, that the effective bulk modulus, thermal expansion coefficient and shear modulus may be expressed as a mixtures estimate plus a correction term, so that
