000015232 520__ $$2eng$$aWe performed a set of cleavage fracture experiments of brittle silicon crystal specimens and compared the energy- speed relationship with continuum-based Freund equation of motion and atomistic simulations. Surprisingly, the continuum- based theory well described the energy-speed relationship at the low energy speed regime. We further performed new set of molecular dynamics simulations and explain why atomistic simulations are still inadequate to describe this relationship. Finally, we suggest a new approach for better atomistic simulations.
