Numerical Prediction of the Bulk Density of Granular Particles of Different Geometries
KONA Powder and Particle Journal, 2014 The Discrete Element Method (DEM) is increasingly used to simulate the motion of granular material in engineering devices. The most widely used shape to model granular particles is the sphere due to its simplicity ...

Individual Particle Motion in Colloids: Microviscosity, Microdiffusivity, and Normal Stresses [PDF]
, 2011 Colloidal dispersions play an important role in nearly every aspect of life, from paint to biofuels to nano-therapeutics. In the study of these so-called complex fluids, a connection is sought between macroscopic material properties and the micromechanics

Combined Influence of Particle Shape and Fabric on the Shear Behaviour of Granular Materials
Advances in Materials Science and Engineering, 2022 The anisotropy feature is an important characteristic of granular materials in natural life and is caused by two facts: the anisotropy feature of particle shape, such as an elongated or flattened shape, and the anisotropy feature of the packing fabric ...

Effects of particle shape on mechanical performance of sand with 3D printed soil analog
Yantu gongcheng xuebao, 2020 At particle scale, the morphological characteristics have a significant effect on the mechanical responses of sand. To analyze such effect, a modified 3D shape factor S ′ is introduced to quantify the particle shape.

Bedload transport in rivers, size matters but so does shape
Scientific Reports, 2021 Bedload transport modelling in rivers takes into account the size and density of pebbles to estimate particle mobility, but does not formally consider particle shape.

Shaping Particles for Ultramicrotomy [PDF]
MRS Proceedings, 1991 AbstractA technique for preshaping large particles of reacted glass for ultramicrotomy is described. This technique preserves delicate surface layers and results in more sections per block extending deeper into the sample than other techniques.
