Density relaxation of granular matter through Monte Carlo and granular dynamics simulations
… One of the most important of these is known as density relaxation. Here, a granular material undergoes an increase in solids fraction as a result of the application of discrete taps or continuous vibrations. In this dissertation, the density relaxation phenomenon is promoted by the application …

Stochastic and deterministic dynamics investigation of the microstructure of granular materials
… compaction that are unknown. In this thesis, the density relaxation phenomenon is modeled using both Monte Carlo and discrete element simulations to investigate the effects of regular taps applied to a vessel having a planar floor filled with monodisperse spheres. Results suggest the existence of …

The effects of surface functionalization on rheology, structure and transport properties of nanocomposites
… We observe an anomalous speed up in the density relaxations and an associated maxima in structure properties in the case of unentangled melts which has been reported previously for particles experiencing soft repulsive potentials. A clear reentrant behavior in structure and transport …

Structure, slow dynamics, kinetic arrest, and massively reconfigurable assembly in colloidal suspensions
… in the ultra-dense regime. At low to moderate density, relaxation times are in agreement with simulation and experiment. In the highly over-compressed regime though, NLE theory appears to miss some longer ranged correlations required to correctly capture the relaxation time growth. Calculations …
