ABSTRACT
The current work attempts to develop a non-ambiguous polyhedron/polyhedron contact algorithm within the energy-based theoretical framework, in which all of the contact characteristics, including the normal/tangential contact direction/plane and contact point are defined uniquely, thereby circumventing the numerical difficulties normally associated with the modelling of polyhedron/polyhedron contact.
