... researched the application of the discrete element method in geotechnical engineering. Cho N, Martin CD et al (2007) explored the influence of the clustering characteristics for particles of rock and soil on the deformation and failure of corresponding materials. Diederich MS (2000) did research...

... and gouge behaviors in fracture voids, the particle mechanics models were used to simulate the process of gouge particle plowed off from fracture asperities and subsequently their evolution in a fracture segment undergoing shear. The results show that significant abrasion and damage occurred by wearing...

... prism was modeled with the smoothed particle hydrodynamics (SPH) method, and the mill structure was modeled by the finite element method (FEM) method. The interaction between the coal specimen and the roller was considered by introducing a master-slave contact boundary. The main aims of this study...

..., and their shapes and sizes, which ranged between a fraction of mm and tens of cm were measured. Frequencies of mass of different particle sizes as well as shapes of particles were determined The particles were typically flat slabs with a thickness 0.1 of the length. They were much thinner at the edges than...

Recent developments in numerical modeling that allow study of the overall response of a synthetic material containing discrete heterogeneities and discontinuities both at the micro (particle) scale and at the larger scale of jointed rock masses can greatly aid...
