title = "Effect of cohesive force on the formation of a sandpile",
abstract = "This paper presents a numerical study on the piling processes of mono-sized wet particles by the discrete element method (DEM). The capillary force between particles due to liquid bridge is implemented in an existing DEM model. The effects of moisture content on the repose angle and structure of a pile are studied by a series of controlled numerical experiments. It is confirmed that the structure of a pile is similar to that of a packing for cohesive particles. Moreover, the averaged local porosity and repose angle have similar changes with the moisture content and can be linearly correlated. Therefore, the relationship between the repose angle and the cohesive force can be established based on the previous correlation between the porosity and the force ratio of the cohesive force to gravity developed in the packing of cohesive particles.",
