Abstract

The nature of the blade fatigue problem is discussed. Factors which are known to influence blade fatigue are the steady and alternating stresses from centrifugal and gasdynamic loading, the material strength properties, crack propagation resistance, chemistry of the working environment, and the time-history of the blade loadings. Major publications from the literature of these topics are reviewed. Important contributions which are influencing current efforts to reduce the number of blade fatigue failures are identified. A general-purpose computer code for blade life evaluation, BLADE, is described. The use of this code for evaluating the expected fatigue life of a six-blade group in an IP steam turbine is demonstrated. The paper contains a reference listing of 59 publications.
