A DEM investigation on crushing of sand particles ...

2020-4-1  Therefore, the major thrust of this paper is to incorporate the information of realistic fracture surfaces of sand particles acquired from CT scanning into the DEM modeling of particle crushing (Wu and Wang, 2019, Wu and Wang, 2018, Wang and Wu, 2020). This is done by randomly choosing 0%, 20%, 40% and 60%, named Case 1, 2, 3 and 4, respectively, of all the contacts intersected by the realistic

A peridynamic investigation on crushing of sand

2019-5-13  In the real engineering context, a sand grain is typically in contact with several surrounding particles and is hence subjected to multi-directional loadings, a critical condition that has not been well accounted for in most crushing criteria and studies of crushing patterns relevant to discrete-based sand modelling. In this study, the crushing of single sand particles under different loading conditions is

A statistical investigation of particle crushing in sand

2011-8-2  ABSTRACT: The deformation of a volume of sand comes about from particle rearrangement to new posi-tions, and from particle crushing at larger stresses. It is desirable to be able to quantify the level of crushing inside a sand, as this affects the grain size distribution of the sample, which is directly linked to its permeabil-ity.

Time Effects Relate to Crushing in Sand Journal of ...

Accordingly, time effects are caused by grain crushing, which in turn is time dependent, as indicated by static fatigue of brittle materials. Triaxial compression tests have been performed on Virginia Beach sand at high pressures, where grain crushing is prevalent, to study effects of initial loading strain rates on subsequent amounts of creep and stress relaxation.
