This paper is a reconsideration and reformulation of the Mori-Tanaka's theory in its
application to the computation of the effective properties of composites. Previous
applications of the theory in this context continued to be linked with eigenstrain, equivalent
inclusion, and back stress concepts, and many times involved energy considerations. In this
paper we adopt the 'direct approach'of defining and computing effective moduli. By
elucidating the nature of the approximation in applying Mori—Tanaka's theory to composites …
