ResumoTurbine bladed disks continue to fail because of fatigue caused by resonant stresses; one of the major failures in the 1990s was reported in a nuclear machine in Narora, India. Bearing failures caused machine trip and rubbing caused blade fatigue (see Figure 18.1). Albert Wilhelm (1838) is recognized as the first person to record observations of metal fatigue. While working in the Mining and Forestry Office in Clausthal, Germany, in 1829, he observed, studied and reported the failure of iron mine-hoist chains arising from repeated small loadings, the first recorded account of metal fatigue, see [31].
