Critical state and constitutive model for coral sand considering particle breakage

Yantu gongcheng xuebao, 2019
The critical state is a very important concept in soil mechanics, and it is the foundation of many constitutive models for soils. As for the coral sand, due to significant particle breakage, its deformation characteristics and critical state are worthy ...

Plastic deformations in crystal, polycrystal, and glass in binary mixtures under shear: Collective yielding

, 2010
Using molecular dynamics simulation, we examine the dynamics of crystal, polycrystal, and glass in a Lennard-Jones binary mixture composed of small and large particles in two dimensions.

Environment-Dependent Breakage Rates in Ball Milling [PDF]

, 1995
Breakage rates of particles in a ball mill change with instantaneous particle size distribution in the mill. Slurry density and the presence of a grinding aid also affect breakage rates substantially.

Influence of fines on the compression behaviour of decomposed volcanic rocks

International Journal of Geo-Engineering, 2019
The compression behaviour of mixtures of sand with fines derived from decomposed volcanic rocks has been investigated in details. Oedometer tests were carried out on the samples of different degrees of weathering.
