| Abstract: | To explore the microscopic responses of granular materials to wetting,the inter-particle lubrication effect and particle breakage in an odometer were simulated using a two-dimensional discrete element method.The lubrication effect was modeled by reduction of the inter-particle friction coefficient and particle breakage was initiated by decreasing the particle strength.Once the strength of the particles decreased to a threshold value,the particles began to break so that new contacts could be established to t... |
