Pressure-Dependent Friction on Granular Slopes Close to Avalanche.

Physical review letters

Crassous J, Humeau A, Boury S, Casas J.
PMID: 28949714
Phys Rev Lett. 2017 Aug 04;119(5):058003. doi: 10.1103/PhysRevLett.119.058003. Epub 2017 Aug 03.

We investigate the sliding of objects on an inclined granular surface close to the avalanche threshold. Our experiments show that the stability is driven by the surface deformations. Heavy objects generate footprintlike deformations which stabilize the objects on the...
