    Abstract

    This paper describes some of the state-of-the-art engineering techniques utilized for the remaining life assessment and condition improvement of steam turbine/generator components in service. These include the finite element method for thermal and stress analyses, the inelastic strain-based fatigue analysis, and fracture mechanics for remaining life assessment. Special techniques for fabricating test specimens from small samples and testing for current fatigue and fracture properties are also described.
