... types of loading: in-phase and out-of-phase cycling. The article illustrates the ways in which damage can interact at high and low temperatures and the development of microstructurally based models in parametric form. It presents a case study of the prediction of residual life in a turbine casing...

... of residual stress (e.g., Ref 39 , 40 , 41 , 42 ) on the RCF life can be significant. Apart from Weibull analysis and the Lundberg-Palmgren theory, other theories of fatigue-life prediction ( Ref 18 ) can also be used. These theories were compared recently using a model roller-race contact and the study...
