OSTI ID:6201190
Fast fracture in brittle materials can be simulated with molecular dynamics. The results have many features in common with macroscopic experiments on real materials. These features include steady propagation of cracks at speeds comparable to the speed of sound; increasing crack velocity with increasing stress; crack inertia, allowing the penetration of cracks into regions which would not fracture under static conditions; and crack-surface irregularity at moderate-to-high temperatures.
