Abstract

We focus attention on homogeneous deformations of a random array of identical spheres that interact through noncentral contact forces. We consider the response of the material in triaxial compression and assume that the displacement of a contact relative to a center may be calculated from the average strain of the aggregate. The normal component of the contact force is Hertzian, while the tangential component of the contact force is assumed to be linearly elastic until frictional slip occurs. For monotone deformations, we calculate the stress-strain response.
