Statistical mechanics of cracks: Fluctuations, breakdown, and asymptotics of elastic theory


We study a class of models for brittle fracture: elastic theory models that allow for cracks but not for plastic flow. We show that these models exhibit, at all finite temperatures, a transition to fracture under applied load similar to the first-order liquid-gas transition. We study this transition at low temperature for small tension. Using the complex… (More)
