Abstract
The discrete element method has advanced significantly since it originated in 1979. This paper aims to provide a selective overview of some major developments on contact modelling methodologies for non-spherical particles in DEM over the last three decades.

The discrete element method has advanced significantly since it originated in 1979. This paper aims to provide a selective overview of some major developments on contact modelling methodologies for non-spherical particles in DEM over the last three decades. More attention is specifically paid towards developments in the early years. This review mainly focuses on the geometric aspects of contact modelling methods without touching upon material related physical issues. Various shape representation schemes for non-spherical particles are first presented using a classification system, followed by the critical review of contact modelling approaches for almost all contact types of non-spherical shapes. In addition to outlining key ideas, concepts and novel computational procedures that are proposed in these methodologies in a systematic and logically constructed manner, their evolutions and inter-relations in particular are also discussed in detail. Moreover, possible problems and unresolved issues for each method reviewed are highlighted, and possible solutions are pointed out where applicable. |
