 · Joints in layered granular rock commonly are perpendicular to the layers (Fig. 6a and b) in which they occur. In both map view and vertical sections joints are short and typically have many segments. For brevity, we refer to the review paper by Pollard and Aydin (1988) on the broad subject of jointing in granular rock and the characteristics of joints.

A review on the angle of repose of granular materials

 · The box must contain at least one transparent side; the granular material is placed on the base of the box, and then the box is tilted gradually at a rate of 18°/min. The angle of repose is then measured as the tilting angle at which the material begins to slide [ 7, 35 ], as shown Fig. 2.

Discrete Simulation of Cone Penetration in Granular …

 · Abstract. The simulation of penetration problems into granular materials is a challenging problem as it involves large deformations and displacements as well as strong non-linearities affecting material behaviour, geometry and contact surfaces. In this contribution, the Discrete Element Method (DEM) has been adopted as the modelling formulation.

 · Therefore, the granular composition of the backfilling rock mass should be well designed, and the granular rock mass should be compressed to reduce the porosity to be as small as possible [21]. It should be pointed out that the present study is only a primary attempt to understand the water and sand inrush through the rock mass.

 · Granular flows of angular rock fragments such as rock avalanches and dense pyroclastic flows are simulated numerically by means of the discrete element method. Since large-scale flows generate stresses that are larger than those generated by small-scale flows, the purpose of these simulations is to understand the effect that the stress level has on flow mobility. The results show that granular ...
