From: Composite materials with enhanced dimensionless Young’s modulus and desired Poisson’s ratio

Young’s modulus of the two-phase composite with the cubic periodic RVE structure shown in Fig. 1 and with EA = 2.0EB and vA = vB vs. the volume fraction of material A, compared with the Voigt limit, the Reuss Limit and the Hashin-Shtrikman upper and lower limits. The Young’s moduli are normalized by EB in Fig. 2.
