摘要：

介绍了离散元法的基本理论、计算方法及其应用的现状和最新进展.从离散元法的离散模型特点及便于甄别与其它数值计算方法的关系的角度给予离散元法一个比较宽松的定义.在此基础上阐明了离散元方法与刚体-弹簧模型(rigid body spring model,RBSM)方法,不连续变形分析(discontinuous deformation analysis,DDA)方法,分子动力学(molecular dynamics,MD)方法,三维离散元(discrete meso-element dynamic method,DM2)方法及无网格方法(meshless method)等数值计算方法的关系,并讨论了离散元法研究中亟待解决的问题和今后的发展方向.
