Biomaterials,During the twentieth century the use of surgery to correct deformities and defects by the use of implants became quite common. Material implants must satisfy a number of requirements. These include strength, durability and chemical reactivity.

Stability in Metallic Elements,to brittle fracture, and can withstand localized overloading. Nominally ductile metals can, however, fracture in a brittle manner under certain conditions. Cyclic loading can result in fatigue cracks that can lead to brittle fracture. Two modes of ductile instability are discussed: time independent loading and time dependent loading, or creep.

Fatigue in Metals,) The role of crack growth in metal fatigue. The Metals Society, London) who indicated that between 1938 and 1983 about 20,000 papers were published on the subject of fatigue. The initial emphasis on fatigue focused on the formation of cracks on smooth surfaces after prolonged periods of cyclic load
