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.

The fabrication of jet engine rotors by joining simple disk and ring shapes offers both weight and cost advantages; however, the metal joints must have excellent and completely reproducible mechanical properties. Inertia welding achieves this since it is a solid state joining process which forges the two parts together under an automatically controlled situation. The parameters for inertia welding jet engine nickel and titanium alloys are discussed. The cost and weight advantages occurring from elimination of mechanical joints and better material utilization are identified. Several typical applications are described.
