Abstract
When a dry non cohesive granular material confined in a box in such a way that the initial profile of the free surface is a horizontal plane and it is accelerated uniformly, the final equilibrium profile changes to a tilted straight plane whose slope is a function of the magnitude of the acceleration, the magnitude of the gravity acceleration and the friction coefficient of the granular material. Here are presented a simple model, based on the Coulomb’s law, that describes correctly such a deformation and some experiments that back the theoretical predictions.
