Interphase Model for Effective Moduli of Nanoparticle-Reinforced Composites
A novel interphase model is constructed based on the double-inclusion theory and the Eshelby tensor in a finite domain, which can be used to calculate the effective material properties of three-phase composites. The refinement of the double-inclusion theory takes into account the effect of a finite matrix and that of a finite interphase. In the model proposed, the multiphase composites are reinforced by different material fillers, which are embedded in a matrix with finite size. The general formulations are derived following the method of Eshelby’s equivalent inclusion. The Dirichlet and Neumann Eshelby tensors for a spherical inclusion in a finite spherical domain are applied to the homogenization of composite materials. By the explicit inversions of the fourth-order tensors involved, the relationships between the elastic moduli of transversely isotropic and orthotropic materials are derived, which are then validated through numerical results from the homogenization of several composites. In addition, the interphase and boundary effects on the effective elastic properties of the composites are investigated.
