Abstract

We present a theoretical model to predict the mechanical behavior of an idealized granular material in triaxial compression. Particle motions involve both the average strain of the aggregate and fluctuations. Force and moment equilibrium determine fluctuations in translation and rotation. Two regimes of deformations are considered: at the beginning of the shearing, the aggregate is assumed to behave elastically; then, when sliding between particles first occurs, the incremental contact forces are assumed to be frictionless. Simulations using the discrete element method are carried out and compared to the predictions of the theory.
