Abstract
Many experimental phenomena concerning microscopic fracture processes have an atomistic origin. The crack tip atom motion excited by fracture is highly nonlinear and chaotic, rendering the atom-istic and chaotic characterizations as essential aspects of fracture processes. In this article, we outline a combined atomistic-continuum formulism for material fracture studies. The chaotic atom motion near a crack tip is explored by using a simplified atom-continuum model, so that an analytical characterization is possible. The phenomena examined under this methodology include catastrophic atomistic cleavage, fracto-emisson, chaos in dynamic cleavage and chaotic dislocation emissions.
