Presentation Title Qualification and Applicability of Fatigue Models for Aeroengine Components

Abstract Scope As a microstructural weakest link, rare-event phenomenon, accurate fatigue life predictions for life-limiting components is one of the greatest challenges facing the materials community. Models must be robust to variations in manufacturing processes and service conditions (stress, temperature, load ratio, dwell time, multiaxial loading, etc.). This presentation will highlight various empirical, physics-based, and hybrid modeling approaches used to predict fatigue lifetime along with the necessary experimental data needed for calibration and validation. In addition to the obvious use of part-life prediction, fatigue models also provide guidance for material selection and process definition. Advances in microstructure characterization and spectroscopy tools have further strengthened our understanding of the mechanisms that control fatigue performance which are being integrated into advanced modeling frameworks which provide a promising outlook for the future of aeroengine component design and lifing.
