Applied Math Seminar: A model for granular statics with impenetrability constraints

Abstract: We study a simple model of quasistatic deformation of granular materials. The model takes into account elastic interaction between the particles and geometric (excluded volume) constraints on the particle positions. In the process of deformation, some interparticle contacts persist, and others are broken. The former contacts are called solid-like. We study geometry of the network formed by the solid-like contacts and show that there are at lest two solid-like contacts per each particle.
