Ductile to Brittle Fracture Transition ... In fracture, there are many shades of gray. Brittle fracture and ductile fracture are fairly general terms describing the two opposite extremes of the fracture spectrum. I will explain the factors that make a material lean toward one type of fracture as opposed to the other type...

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 ...

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 fracture has dimpled, cup and cone fracture appearance. The dimples can become elongated by a lateral shearing force, or if the crack is in the opening (tearing) mode. ... Ductile fracture is characterized by tearing of metal and significant plastic deformation. The ductile fracture may have a gray,

In this paper, we describe a method for realistically animating ductile fracture in common solid materials such as plastics and metals. The effects that characterize ductile fracture occur due to interaction between plastic yielding and the fracture process.

Ductile fracture is preceded by substantial plastic deformation. When a material contains relatively hard inclusions which do not deform at the same rate as the matrix, voids are nucleated to accommodate the incompatability.
