Friction measurements in granular media.
We present some experimental results, estimating the lateral stress response to a longitudinal stress applied to an ideal granular system as a function of friction parameters. Structural effects are taken into account through the use of an angle of contact distribution. The two-dimensional model, based on mainly equally sized cylinder granules allows one to derive a dependency of the friction between single granules and the overall angle of friction, which is commonly used to describe the macroscopic behavior of granulate material.
