Liability of breakage from stress without significant plastic deformation / From Wikipedia, the free encyclopedia
A material is brittle if, when subjected to stress, it fractures with little elastic deformation and without significant plastic deformation. Brittle materials absorb relatively little energy prior to fracture, even those of high strength. Breaking is often accompanied by a sharp snapping sound.[citation needed]

Brittle materials include most ceramics and glass (which do not deform plastically) and some polymers. Some metals become brittle at low temperatures (see ductile-brittle transition temperature) depending on their composition and processing.
