Advanced High Cycle Fatigue (HCF) Life Assurance Methodologies

Abstract

This program was a follow-on effort to a program on Improved High Cycle Fatigue (HCF) Life Prediction, USAF Contract F33615-96-C-5269, the results of which are documented in the final report on that PRDA program 1. This program continued work on addressing key issues associated with developing, verifying, & implementing a material damage tolerant design methodology capable of predicting HCF limits & material thresholds for Ti-6Al-4V. The methodology development was extended to another titanium alloy, Ti-17, and to a nickel-base single crystal alloy, PWA 1484.
