Granular Material - an overview | ScienceDirect …
When granular materials are strongly forced, e.g. by shearing, all frictional bonds can be broken and the material can be fluidized. In this state, known as ‘rapid granular flow’, the stone interactions are practically instantaneous inelastic collisions and as such the state of the system is reminiscent of that of a (classical) molecular gas.
Bulk material - Schrage
Bulk material. The term “bulk material” is used to refer to a granular or lumpy mixture existing in a free-flowing form. A bulk material’s properties are defined by its stone size and stone size distribution, as well as by its bulk density, angle of repose, moisture, and temperature.

Characterization of Granular Material
granular material and an estimation of residual stresses induced by compaction are presented. An analysis of a layered system is included to illus trate the effect of residual stresses on the moduli of granular material and to compare the results with values used in existing pavement design procedures.

Bulk Material Density Guide | Hapman | Ideas That …
You need to know bulk density to work with any powder or bulk solid. This guide listing thousands of materials is meant as a reference tool to assist you in designing your production system. Because the bulk density of a substance varies greatly depending on how the material has been handled, the information contained in this reference tool should be used for estimation purposes only.
Materials | Special Issue : Granular Materials
Thermally-assisted compaction of granular materials is of keen interest in many engineering applications. A proper estimation of the material behavior of compacted granular materials is contingent upon the knowledge of microstructure formation, which is highly dependent on the bulk material properties and processing conditions, during the deformation stage.
PACKING OF GRANULAR MATERIALS
Granular materials are prevalent in the world at macro and micro scales, from the macro-scale of construction materials to the micro-scale of stone powders. The properties of assemblages of grains are heavily controlled by the interparticle contacts.
