Effects of Spectrum Block Size and Stress Level on Fatigue Characteristics of Aluminum Alloy Box Beams under Random-Sequence Unidirectional Loading.
Abstract
The results of random-sequence fatigue tests of 7075-T6 aluminum-alloy box beams in unidirectional bending are presented. The relative damaging effect of four airplane flight-maneuver-loads spectra was determined, and the effects on life for variation in spectrum block size and stress level were established. The effects of load sequence on life were determined through comparison and analysis of these data with that for fixed-sequence loading of a previous investigation. (Author)
