Investigation of Fatigue Crack-Growth Resistance of Aluminum Alloys under Spectrum Loading.

Abstract

The purpose of this program is to obtain metallurgical guidelines and test methodologies for selection and development of spectrum fatigue resistant, high strength aluminum alloys for application to aircraft structures. Described in this report are the results of baseline characterizations of ten high strength aluminum alloys. Also described are results of fatigue crack-growth tests under two F-18 load spectra and under modifications of these spectra.
