, 2003 Dynamical behavior of steady granular flow is investigated numerically in the inelastic hard sphere limit of the soft sphere model. We find distinctively different limiting behaviors for the two flow regimes, i.e., the collisional flow and the frictional

Force Mobilization and Generalized Isostaticity in Jammed Packings of Frictional Grains [PDF]
, 2006 We show that in slowly generated 2d packings of frictional spheres, a significant fraction of the friction forces lies at the Coulomb threshold - for small pressure p and friction coefficient mu, about half of the contacts. Interpreting these contacts as

Contact problems with friction: models and simulations [PDF]
Simulation Modelling Practice and Theory, 2003 This article deals with the modeling and the numerical simulation of contact and friction problems. Some friction formulations are proposed and numerical methods of resolution by finite elements are presented. Two methods are more particularly developed.

Nonmonotonic Aging and Memory in a Frictional Interface
, 2017 We measure the static frictional resistance and the real area of contact between two solid blocks subjected to a normal load. We show that following a two-step change in the normal load the system exhibits nonmonotonic aging and memory effects, two ...

Existence for viscoplastic contact with Coulomb friction problems
International Journal of Mathematics and Mathematical Sciences, 2002 We present existence results in the study of nonlinear problem of frictional contact between an elastic-viscoplastic body and a rigid obstacle. We model the frictional contact both by a Tresca's friction law and a regularized Coulomb's law. We assume, in

ZMP support areas for multi-contact mobility under frictional constraints [PDF]
, 2016 We propose a method for checking and enforcing multi-contact stability based on the Zero-tilting Moment Point (ZMP). The key to our development is the generalization of ZMP support areas to take into account (a) frictional constraints and (b) multiple ...
