Structural Evaluation of an Extruded Magnesium-Alloy T-Stiffened Panel

Abstract

Compressive tests were made of six different lengths of a ZK60A magnesium-alloy flat panel having skin and longitudinal T-section stiffeners extruded as one integral unit. The results indicated that the extruded panel had structural characteristics which were somewhere between those for 24S-T and those for 75S-T aluminum-alloy Y-stiffened panels but, because of the integral nature of the extruded construction, required far fewer rivets to assemble than either the 24S-T or the 75S-T panels with which comparisons were made. The height of the stiffeners was also somewhat less for the extruded panel.
