Abstract

We discuss both theory and simulation of fracture of ideal and almost ideal crystals at finite temperature. We propose that a solid under stress is in a metastable state, and that the onset of fracture may be characterized as the nucleation of the (stable) broken phase from the (metastable) intact phase. The role of atomic-scale defects is also discussed.
