Abstract.

This paper reports the numerical results of the effective moduli of a composite consisting of identical rigid spherical inclusions in a homogeneous isotropic elastic medium. The effective moduli are calculated for particles in simple, body-centered, face-centered cubic lattices, and in a random configuration. The numerical technique used is the Completed Double Layer Boundary Element Method (CDLBEM) augmented by a short-range lubrication approximation. The results agree well with previous numerical results obtained by a completely different technique. Agreement with experimental results for particles in random configurations is also observed.

Key words. Particulate solids, boundary element method, completed double layer BEM, lubrication approximation, effective moduli, contitutive equations, micromechanics.
