Establishing a Foundation for Real Physics-Based Fatigue Failure Predictions of Sea-Based Aircraft

Abstract

This project will apply state-of-the-art atomistic based simulation techniques to advance themechanistic understanding and models of fatigue crack initiation in naval aviation. Specifically,the project is aimed at (1) bridging the gap between existing fatigue initiation models and realworldservice conditions, (2) providing mechanistic based material separation rules formicrostructural models, and (3) identifying nanoscale routes for improved fatigueperformance/mitigation via new alloys, coatings, and/or treatments. Broadly, improved fatigueprediction capabilities may translate to fewer unexpected failures, decreased ownership costs, andthe increased availability of existing aircraft.
