Example of brittle material
WebIn materials science, brittleness is understood as the lack of ductility. For engineers, the understanding of the difference between brittle and ductile material is of the highest … 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. When used in … See more Polymers Mechanical characteristics of polymers can be sensitive to temperature changes near room temperatures. For example, poly(methyl methacrylate) is extremely brittle at … See more Materials can be changed to become more brittle or less brittle. Toughening When a material has reached the limit of its strength, it usually has the option of either deformation or fracture. A naturally malleable metal … See more Supersonic fracture is crack motion faster than the speed of sound in a brittle material. This phenomenon was first discovered by scientists from the Max Planck Institute for Metals Research See more • Charpy impact test • Ductility • Forensic engineering See more
