Examples: Large-scale simulation of crack propagation Molecular dynamics simulation with ~1 billion atoms illustrates crack propagation in a ductile metal. At first, the crack moves very rapidly and local bonds break in a "brittle" manner, but at some point the crack-tip begins to emit dislocations (the tangles in the picture) and stops propagating. Such a crack is said to become blunted and begins to cause intense local deformation but not failure. by F. F. Abraham et al.
