27), we obtain two exact expressions. 28) 44 H. L. Duan et al. ¯ L + 4k¯ ν¯ 2 , ρ0 is the radius of the fibers, and αsT and αsL where ¯l = 2k¯ ν¯ L , n¯ = E L are the interface CTEs in the transverse direction and in the longitudinal direction, respectively. The two equalities prove that only three of the five effective elastic moduli are independent. Eq. 28) is identical to Eq. (13) in the paper of Chen and Dvorak (2006). The two equalities Eq. 28) reduce to Hill’s connections (Hill, 1964) when λs = 0 and μs = 0.

For GSCM, the constants ak and bk (k = m, e) need to be determined from the remote boundary conditions in Eq. 44) and the boundary and interface conditions in Eqs. 36). 46) ∗ (1 + f)μLm + (1 − f)μTm C1212 m . where μLm = C1212 (d) Transverse Shear Modulus μ ¯ T . As the composite cylinder assemblage model (CCA) only gives bounds on the effective transverse shear modulus, we only use the GSCM to calculate μ ¯ T . For this, as in the work of Christensen and Lo (1979), the imposed remote strain field in this model is chosen as ε0xx = −ε0yy = ε0T , and the corresponding remote displacements (ρ → +∞) in the cylindrical coordinate system are u0ρ = ε0T ρ cos 2φ, u0φ = −ε0T ρ sin 2φ, u0z = 0.

2. Prediction of Elastic Moduli by MTM For a composite with spherical nano-inhomogeneities, the configuration of MTM is a spherical nano-inhomogeneity with radius r = R embedded in an infinite matrix subjected to an imposed remote field equal to the as-yet-unknown average stress (strain) field in the matrix of the composite. Similar to those for predicting the effective bulk modulus by CSA, the boundary displacements and the displacement component for finding the bulk modulus of the composite are still given by Eqs.
