Figure 1: The different types of crack formation predicted to occur in a brittle solid when the size of the system or the amount of disorder is varied. (Note that zero on the plot corresponds to maximum disorder and infinite size.) Three distinct regions are observed: Percolation (pink region), where small cracks trickle through the material; avalanches (yellow region) where small cracks branch into larger ones; and nucleation (white region) where a large single crack forms.
