Effects of grain size distribution on the initial strain shear modulus of calcareous sand [PDF]

, 2015
The soil’s small strain shear modulus, Gmax or G0, is applied in dynamic behavior analyses and is correlated to other soil properties (density and void ratio) for predicting soil dynamic behavior under seismic loadings such as earthquakes, machinery or ...

The Effect of Particle Strength on the Ballistic Resistance of Shear Thickening Fluids

, 2013
The response of shear thickening fluids (STFs) under ballistic impact has received considerable attention due to its field-responsive nature. While efforts have primarily focused on the response of traditional ballistic fabrics impregnated with fluids ...

Photoluminescence of single colour defects in 50 nm diamond nanocrystals

, 2005
We used optical confocal microscopy to study optical properties of diamond 50 nm nanocrystals first irradiated with an electron beam, then dispersed as a colloidal solution and finally deposited on a silica slide.

Micro shape of coal particle and crushing energy

International Journal of Mining Science and Technology, 2018
A large amount of energy is consumed in a coal and gas outburst since a mass of coal is pulverized and ejected, accompanying a great quantity of gas emitted, resulting in a major mining hazard in underground coal mining around the world.

Elastoplastic constitutive model for granular materials considering meso-particle damage

Yantu gongcheng xuebao
Establishing a constitutive model for granular materials that accounts for particle shape and breakage mechanisms has been crucial for calculating the mechanical stability of earth-rock dam projects. Initially, through the triaxial compression tests, the
