Analysis of Widespread Fatigue Damage in Aerospace Structures

Abstract

This report summarizes research dealing with analyzing the effects of widespread fatigue damage on aircraft structural integrity. Results are described for determining how cracks nucleate by corrosion, fatigue, or fretting fatigue, and once formed, grow, coalesce and lead to final fracture. The research is conducted in the context of the aging aircraft issue, which focuses on determining procedures for ensuring the continued safety of aircraft that operate beyond their original design lifetimes.
