Shear Deformation in Granular Material
An investigation into the properties of granular materials is undertaken via numerical simulation. These simulations highlight that frictional contact, a defining characteristic of dry granular materials, and interfacial debonding, an expected deformation mode in plastic bonded explosives, must be properly modeled. Frictional contact and debonding algorithms have been implemented into FLIP, a p...
متن کاملGranular material flows – An overview
The paper attempts to give a critical overview of the field of granular flow with attention both to the history and the underlying physics that govern the field. It starts with a discussion of the basic transport mechanisms in a granular flow. It continues with a discussion of contact mechanics – the way that individual particles see each other mechanically. It then discusses the historical lim...
متن کاملShakedown of unbound granular material
Compacted unbound granular materials are extensively used as sub-layer in pavement design. Most pavement design guides assume that they are responsible for the degradation and deformation of the roads and railways that they support. Biaxial tests are usually employed to investigate the elasto-plastic response of these materials to cyclic loading. A particularly interesting question is whether a...

متن کاملCrystallisation in a granular material
The athermal and dissipative nature of packings of grains is still challenging our understanding of their compaction as well as their crystallisation. For instance, some beads poured in a container get jammed in random disordered con gurations, which cannot be denser than 64%, the random closed packing (RCP) limit. Remarkably it has been suggested that the RCP bound is saturated with dense patt...
