Cell Size Effects in Characterizing Dry Quartz Sand Particles
Only a limited number of atoms is generally used in molecular mechanics analysis to reduce the computation time, which will be exhaustive otherwise. This paper analyzed the cell size effects in characterizing fundamental properties of a dry quartz grain using molecular mechanics. In order to find the minimum number of atoms that produces the representative material properties, this study performed the numerical analysis for different cell sizes. This study also analyzed the cell size effects in particulate mechanics simulations which essentially characterize the assemblage properties of quartz sand grains. From this research, it turned out that four times the unit cell size is required as a cell size to obtain representative properties of a quartz grain in molecular mechanics simulation. It also turned out that about ten times the grain size is required as a cell size to obtain representative properties of a quartz sands assemblage.
