Item Description: The treatment of contact conditions in discrete element models has traditionally been based on simple engineering principles and heuristic approaches. This paper establishes a unified and energetically based formulation for contact modelling applicable to arbitrary shaped particles, which has a clear geometrical interpretation and can recover well-known models used in practice. The approach is well accepted and implemented in commercial codes, including Rockfield’s discrete element system ELFEN (j.rance@rockfield.co.uk).
