Macroscopic elastic moduli are derived for a composite material containing many ellipsoidal reinforcements whose semi-axes are different from each other by using the equivalent inclusion method combined with the Mori-Tanaka theorem. In the analysis, Eshelby tensor for the reinforcement is rearranged in the form of a function of Poisson's ratio of the matrix multiplied by the geometrical factor which is a function of the only aspect ratios of reinforcement. Since the composite has two perpendicular twofold rotations symmetry, the number of independent macroscopic elastic moduli may be expected to be nine. Under the applied normal stresses, three macroscopic elastic moduli and three Poisson's ratios of the composite are expressed by the geometrical factor successfully.
