Abstract
We have coupled the continuum, the atomistic, and the quantum descriptions of matter for a unied treatment of the dynamic fracture of silicon. We have devised schemes for handshaking between the nite-element, molecular dynamics and semi-empirical tight-binding representations. We illustrate and validate the methodology for brittle crack propagation in silicon.Keywords
