Abstract

We present an experimental study about the stability and dynamics of a granular packing and the influence of the packing size on the avalanche mass and on its characteristic angles: maximum angle of stability and angle of repose.

For a system with a large enough number of granular layers only Nc superficial layers contribute to the avalanche mass. It can be observed that Nc strongly depends on the packing size. Experiments are done on monosize glass beads with packings of different sizes.
