Numerical simulations were carried out to examine the flow of dry granular materials around obstacles. Two numerical approaches were used. The first is a single-phase formulation based on a Particle-In-Cell (PIC) approach, and employs simplified expressions for the granular stresses. The second appr

This paper describes the computer algorithms used in a numerical simulation of the compression of an aggregate of crushable grains. It has been used in a model for the evolution of a granular medium under one-dimensional compression, in which the probability of fracture for individual particles is a
