A REVIEW ON THE DISCRETE ELEMENT METHOD

LIU Kaixin GAO Lingtian Department of Mechanics and Engineering Science, Peking University, Beijing 100871, China  
This paper summarizes the recent progress in theoretical bases, numerical algorithms and applications of the discrete element method (DEM). A more general definition for the DEM is made, by considering the key point of the model and its distinctions from the other numerical algorithms. The relationship between the DEM and the other algorithms, such as RBSM (Rigid Body Spring Model), DDA(Discontinuous Deformation Analysis), MD(Molecular Dynamics), DM2 (Discrete Meso-element Dynamic Method), MM(Meshless Method), is explained. The future research topics and development tendency of the DEM are discussed.
