✦ Synopsis

This paper analyzes relationships allowing global variables to be deduced from local ones in granular materials. This change of scale is now clear for static variables but rather confusing for kinematic variables. This paper compares the various established formulations for kinematic variables and also proposes original formulations. By running numerical simulations all the formulations in question are compared and the basic premises to define the change of scale for kinematic variables in granular media put forward.

This paper is dedicated to the analysis of the local phenomena which give rise to anisotropy in granular materials. This anisotropy can be observed for small strains (''elastic strains'') as well as large irreversible strains (''plastic strains''). Elastic anisotropy appears to be due to the distrib
