What Does Brittle Fracture Mean?

A brittle fracture is the fracture of a metallic object or other material without appreciable prior plastic deformation. It is a break in a brittle piece of metal that failed because stress exceeded cohesion. The brittle fracture of normally ductile steels occurs primarily in large, continuous, box-like structures such as:
Box beams
Pressure vessels
Tanks
Pipes
Ships
Bridges
Other restrained structure
Brittle fractures that occur in service are invariably initiated by defects that are initially present in the manufactured product or fabricated structure, or by defects that develop during service.
