In this paper we propose to construct a mean stress tensor for a granular medium, valid in static and in dynamics, which takes into account the contact reactions and the body forces acting at the grain level. A simple analytical example shows that taking account of inertia forces is essential to ins
The aim of this paper is to construct an averaged stress tensor for a granular media, valid in static and in dynamics, which takes into account the contact reactions and the body forces acting at the grain level. The construction, based on a simple formula of linear algebra, is inspired from the Cau
This paper constructs the simplest model of granular matter such that the equations for the force distribution in the material can be derived and solved for simple geometries. This will be done by writing down an integral equation for the force field (which reflects the ability of athermal, friction
As an application of the model we have developed for the stress within a granular material we consider the force distribution within vertical and horizontal pipes. For a vertical pipe (with rough walls) the average forces in the system follow the arch of a catenary between the walls. For a horizonta
