A Comparison between Angle of Repose and Friction Angle of Sand
ABSTRACT: It may be said that the shape of sand deposition is normally cone and sand grains are oriented a certain angle of deposition repose is made. This angle is such that no stability occurs. Thus the angle of repose is somewhat correlated to the sand internal friction angle. This paper presents the results of a series of laboratory experiments performed three types of sand. For this purpos...
متن کاملDynamics at the Angle of Repose: Jamming, Bistability, and Collapse
When a sandpile relaxes under vibration, it is known that its measured angle of repose is bistable in a range of values bounded by a material-dependent maximal angle of stability; thus, at the same angle of repose, a sandpile can be stationary or avalanching, depending on its history. In the nearly jammed slow dynamical regime, sandpile collapse to a zero angle of repose can also occur, as a ra...
متن کاملCone: A Distributed Heap Approach to Resource Selection
In this paper, we propose a new distributed heap-based data structure called Cone. Cone maintains an ordering of key values in a distributed fashion, and can support queries of the form, “Find resources of size .” Cone can be built on any routing substrate as long as the substrate supports longest prefix match-based lookups. We describe the Cone data structure, the operations it supports, and i...
