The assessment of fatigue-creep life of hot engine components either using conventional safe life design approach or damage tolerant design concepts require the computation and evaluation of the stress-strain-temperature-time cycles corresponding to the operational sequences. For typical jet engine operations the temperature and elastic stress-strain states for an uncooled turbine blade were calculated using finite elements. A primary concern was the aspect of multiaxiality and associated non-proportionality. The results are discussed in regard to multiaxial equivalent damage concepts.

Code Procedure

A method is proposed for ASME Section III fatigue evaluations which can be applied in the elastic or plastic ranges with constant or varying principal stress/strain directions. The generality of the method is demonstrated. For biaxial or triaxial loadings, the method is shown to be more consistent than the Code procedure given in NB-3228.1.
