Crack spreading in brittle solids such as rocks or ceramics involves mechanisms that span a vast range of scales: a, macroscopic metre-scale events, for example rock fracture caused by an earthquake; b, mesoscopic micrometre-scale evolution of cracks; c, atomistic nanometrescale details of the geometry of the crack tip; and d, breaking of chemical bonds at the angstrom scale. Via.
