摘要：

This paper describes a three‐dimensional discrete element method of analysis for granular materials. Individual particles are modelled as rigid, six‐sided solids with six degrees of freedom. Various types of contacts are possible among the three‐dimensional discrete elements. Models for these contact types are described. Computational aspects of the method, such as techniques for contact detection and data structure, are addressed. Selective results of three examples that demonstrate the application of the method to granular flow problems are presented and discussed. Copyright © 1990 John Wiley & Sons, Ltd
