• In this paper, it is evaluated global averages of elastic properties for particle-reinforced composite materials including spherical inclusions, using a three dimensional analysis based on the finite element method. In the numerical analysis, it is assumed that particles of the same radius are arrayed in body-centered cubic. The volume fraction of the composite material is determined by the radius of particles. A cube including tow particles is as a unit cell and given forced-displacement. And then the global Young's modulus and the global Poisson's ratio of the composite material are obtained from the reaction forces. As an example, it is considered that a composite material consists of epoxy and glass. The obtained results are compared with results by methods based on the Eshelby's equivalent inclusion theory.
