Flows of granular material in two-dimensional channels [PDF]
, 2015 Secondary cone-type crushing machines are an important part of the aggregate production process. These devices process roughly crushed material into aggregate of greater consistency and homogeneity.

Advances in Materials Science and Engineering, 2015 Crushing of rock particles is a phenomenon commonly encountered in geotechnical engineering practice. It is however difficult to study the crushing of rock particles using classical theory because the physical structure of the particles is complex and ...

On the micro mechanics of one-dimensional normal compression [PDF]
, 2015 Discrete-element modelling has been used to investigate the micro mechanics of one-dimensional compression. One-dimensional compression is modelled in three dimensions using an oedometer and a large number of particles, and without the use of ...

GEOMATERIAL SINGLE PARTICLE CRUSHING CHARACTERISTICS
Doboku Gakkai Ronbunshu, 2001 本研究では, 8種類の試料に対し単粒子破砕試験を実施し, 砂の単粒子破砕特性に与える粒子の形状, 鉱物, および大きさの影響についての考察を行った. その結果, 粒子が破砕するときの形態には, 何種類かのパターンがあること, また破砕のパターンと粒子の形状, 粒子の構成鉱物とは密接に関連していることが明らかとなった. さらに単粒子破砕強度と粒子の大きさや形状とに相関がみられた.

On the measurements of individual particle properties via compression and crushing
Journal of Rock Mechanics and Geotechnical Engineering, 2021 An experimental study is presented to measure the elastic, yielding, and crushing properties of individual particles under compression using substrates made of aluminum alloy, stainless steel, and sapphire. Carefully selected, highly spherical individual

Experimental investigation of stress rate and grain size on gas seepage characteristics of granular coal [PDF]
, 2017 Coal seam gas, held within the inner pores of unmineable coal, is an important energy resource. Gas release largely depends on the gas seepage characteristics and their evolution within granular coal.

Fractal crushing of solid particles
KSCE Journal of Civil Engineering, 2017 It does not have widely accepted theory to study particle crushing up to now because of the complex and irregular physical structure of the particles. Fractal theory, which employs statistical concepts in order to explain particle crushing, may provide a solution to this problem.

SPH calculations of asteroid disruptions: The role of pressure dependent failure models [PDF]
, 2015 We present recent improvements of the modeling of the disruption of strength dominated bodies using the Smooth Particle Hydrodynamics (SPH) technique. The improvements include an updated strength model and a friction model, which are successfully tested ...

Binary-induced collapse of a compact, collisionless cluster [PDF]
, 1999 We improve and extend Shapiro's model of a relativistic, compact object which is stable in isolation but is driven dynamically unstable by the tidal field of a binary companion.
