Frangibility : ウィキペディア英語版 | Frangibility
A material is said to be frangible if through deformation it tends to break up into fragments, rather than deforming elastically and retaining its cohesion as a single object. Common biscuits or crackers are examples of frangible materials, while fresh bread, which deforms elastically, is ''not'' frangible. A structure is frangible if it breaks, distorts, or yields on impact so as to present a minimum hazard to the vehicle. A frangible structure is usually designed to be frangible and to be of minimum mass. ==Smoke outlets==
Frangible pavement lights or smoke outlet panels may be placed in the pavement in front of a building, to allow these areas to be broken and smoke to escape from the basement in case of fire. These are commonly found in London, for example, where the frangible area may be outlined by a metal demarcation strip, generally of brass or stainless steel.
