Compressive-Strength Comparisons of Panels Having Aluminum-Alloy Sheet and Stiffeners with Panels Having Magnesium-Alloy Sheet and Aluminum-Alloy Stiffeners
Abstract
Comparisons are made of 24S-T aluminum-alloy flat compression panels having longitudinal Z-section stiffeners, and panels having flat FS-1H magnesium-alloy sheet and longitudinal 24S-T aluminum-alloy Z-section stiffeners. It is shown that composite magnesium-alloy panels have higher structural efficiencies and buckling loads if stiffeners are widely spaced. If stiffeners are closely spaced, or if panels have ideal proportions, structural efficiencies are nearly the same, except in a small range of loading conditions in which 24S-T aluminum-alloy panels have slightly higher structural efficiencies.
