Publisher Summary The discrete element method is very significant for simulating the behavior of granular materials, such as sands and rocks. The initial formulation and a large number of current implementations are based on models that employ spherical particles with varying diameter. This chapter presents a three-dimensional particle-clustering technique for the solution of particulate problems. Particles are generated by first creating disconnected tetrahedral elements and then placing overlapping spheres at the comers of the tetrahedra. The irregular shape of these particles leads to more realistic simulations. The chapter presents two examples of sand flow through an hourglass and particles in a rotating tumbling mill for the verification of this technique. |
