Single Particle Crushing

Particle-scale mechanics of sand crushing in compression and shearing using DEM

In this paper, the discrete element method is used to explore why differing amounts of breakage, quantified using Hardin’s relative breakage parameter (Br), are associated with the critical state line (CSL) and the normal compression line (NCL) at similar stress levels. Virtual samples initially containing more than 20,000 spherical particles were isotropically compressed to a range of confinin...

effect of particle crushing on shear strength and dilation characteristics of sand-gravel mixtures

there are limitations in experimental studies on sand-gravel mixtures due to the small size of testingspecimens. due to this problem, many researchers have worked on prediction of the shear strength of mixture by testingthe sandy fraction of soil alone and developed empirical relationships. most of the previous relationships have beendetermined for low surcharge pressures in which particle brea...

Entanglement in single-particle systems

We address some of the most commonly raised questions about entanglement, especially with regard to the so-called occupation number entanglement. To answer unambiguously whether entanglement can exist in a one-atom delocalized state, we propose an experiment capable of showing violations of Bell’s inequality using only this state and local operations. We review previous discussions for one-phot...
