On the other hand, in dealing with brittle fracture, cracks spread very rapidly with little or no plastic deformation. The cracks that propagate in a brittle material will continue to grow and increase in magnitude once they are initiated.

A fracture is the (local) separation of an object or material into two, or more, pieces under the action of stress. The word fracture is often applied to bones of living creatures, or to crystals ...

We investigate the physical meaning of the intrinsic crack resistance in the Griffith theory of brittle fracture by means of atomic-scale simulations. ... By taking cubic SiC as a typical brittle material, we show that the widely accepted identification of intrinsic crack resistance with the free surface energy...

Toughness is crucial to the structural function of bone. ... We find that the fracture energy changes by two orders of magnitude depending on the collagen orientation, and the angle between collagen and crack propagation direction is decisive in switching between different toughening mechanisms.

Ductile metals experience observable plastic deformation prior to fracture. Brittle metals experience little or no plastic deformation prior to fracture. At times metals behave in a transitional manner - partially ductile/brittle.

ScienceDaily (Nov. 19, 2003) — Materials scientists have discovered the conditions under which cracks can propagate supersonically in brittle solids. ... Therefore, the scientists conclude that hyperelasticity is crucial for understanding and predicting the dynamics of brittle fracture.
