Abstract
Recent experience with cracking of the outer surface of load-cycled, high-pressure, steam-turbine rotors is analyzed as a thermal stress-fatigue problem. Cyclic strains are evaluated as a function of the operating transient and of the detailed rotor geometry. Operating recommendations are given with the aim of reducing the incidence of such cracking.
