Improved Navy Maintenance Through Corrosion-Fatigue Assessment Program

Abstract

The High-Strength Steel Corrosion-Fatigue Assessment program was designed to ensure reliability and supportability of current and emerging Naval aircraft by providing requisite engineering support to evaluate issues relevant to corrosion-fatigue of aircraft components. In this multi-year, multi-contract program, tools have been developed to assist in the establishment of maintenance options for corroded components. Experimental and analytical tools have been developed to classify corrosion in a manner tied to a reduction in fatigue life, to assess corrosion classifications by corrosion metrics, to measure these metrics with nondestructive methods, and to model the effect of corrosion on fatigue life. This report describes the work accomplished during the second two years and second contract of the program.
