TLDR
The unilaterality of non penetration constraints, the velocity jumps which occur in case of collisions, and the irregularity of the law of dry friction are 'nonsmooth features of the dynamical systems in view' as discussed by the authors.Abstract:
The unilaterality of non penetration constraints, the velocity jumps which occur in case of collisions, the irregularity of the law of dry friction are 'nonsmooth features of the dynamical systems in view. Numerical methods are presented, which face nonsmoothness without resorting to mollifying approximation procedures. A careful formulation of contact laws generates algorihms which, at every step of the time discretization, are ready to face possible collisions on the same footing as permanent contactsread more

Patterns and collective behavior in granular media: Theoretical concepts
Igor S. Aranson,Lev S. Tsimring +1 more
TL;DR: In this paper, the authors survey a number of situations in which nontrivial patterns emerge in granular systems, elucidates important distinctions between these phenomena and similar ones occurring in continuum fluids, and describes general principles and models of pattern formation in complex systems that have been successfully applied to granular system.

Cohesive, frictional powders: contact models for tension
TL;DR: In this paper, a contact model involving the physical properties of elastic-plastic repulsion, dissipation, adhesion, friction as well as rolling and torsion-resistance is presented.

Granular Matter: A Tentative View
TL;DR: In this article, the shape of the heap and the stress distribution inside depend critically on how the heap was made, and hence come many difficulties, such as how the sand remains as a heap.

The granular column collapse as a continuum: validity of a two-dimensional Navier–Stokes model with a μ(I)-rheology
TL;DR: In this article, a Navier-Stokes solver is used to simulate the column collapse of granular columns over a wide range of aspect ratios in the case of a steady infinite two-dimensional granular layer avalanching on an inclined plane.
