This research represents a coupled atomistic and continuum                mechanics study of the mechanical properties and response of                    interfaces in bicrystals.  Computer modeling will be used                       extensively.  Although the emphasis is on grain boundaries, the                 results will also relate to bi-material interfaces, such as in                  composites.  Atomistic calculations using many-body potentials                  will be compared with the results obtained by a continuum                       mechanics treatment in order to determine the required interface                continuity conditions.  Later, the research will concentrate on                 grain boundary cracks.  A major objective of this                               research is to develop the ability to incorporate interfacial                   properties into the continuum treatments of interfacial cracks.
