Fracture mechanics

Fracture mechanics is the field of mechanics concerned with the study of the propagation of cracks in materials. It uses methods of analytical solid mechanics to calculate the driving force on a crack
The S.S. Schenectady split apart by brittle fracture while in harbor, 1943.
Fracture toughness

In materials science, fracture toughness is the critical stress intensity factor of a sharp crack where propagation of the crack suddenly becomes rapid and unlimited. It is a material property that qu

…range of the stress intensity Δ K experienced by the crack due to the applied loading. Fast fracture will occur when the stress intensity exceeds the fracture toughness of the material. The prediction of crack growth is at the heart of the damage tolerance mechanical design discipline. The processes of material…
Morphology of fracture surfaces in materials that display ductile crack growth is influenced by changes in specimen thickness.
