Abstract
Various aspects of the use of a fracture mechanics approach to steam turbine rotor design are covered in this chapter. The importance of using proper operational procedure to prevent brittle fracture is reviewed, and various methods of estimating toughness properties from small amounts of material are discussed. Some practical aspects of disc bursting are covered, and a probabilistic approach to design is introduced by way of an example problem.
