Importance of Micro/Macro Interaction in the Mechanism of Brittle Mode Cutting

The mechanism of brittle mode cutting has been investigated from the viewpoint of the micro/macro interaction. The concept of micro/macro interaction is first described briefly, and the method to incorporate the concept into the Variable Resolution Molecular Dynamics (VRMD) has been discussed, together with the explanation of the VRMD itself. The results of the VRMD without, with incomplete and with complete micro/macro interaction have been compared and the crucial role of the interaction has been clarified.
