Where does a cohesive granular heap break?
L. Bocquet, F. Restagno, E. Charlaix
In this paper, we consider the effect of cohesion on the stability of a granular heap. We first briefly review literature results on the cohesion force between two rough granular b…
Slow Kinetics of Capillary Condensation in Confined Geometry: Experiment and Theory
F. Restagno, L. Bocquet, J. Crassous +1
When two solid surfaces are brought in contact, water vapor present in the ambient air may condense in the region of the contact to form a liquid bridge connecting the two surfaces…
Humidity Effects and Aging Behavior in Granular Media
F. Restagno, H. Gayvallet, L. Bocquet +1
We present a study of humidity effects on the maximum stability angle in granular media. We show that a granular medium of small glass beads exhibits aging properties : the first a…
Moisture induced Ageing in Granular Media
L. Bocquet, E. Charlaix, S. Ciliberto +1
We present experiments showing that a granular system of small beads does exhibit ageing properties : its maximum stability angle is measured to increase logarithmically with resti…
