Design Development and Durability Validation of Postbuckled Composite and Metal Panels. Volume 4. Design Guide Update
Abstract
The objective of this program was to develop design procedures and durability validation methods for curved metal and composite panels designed to operate in the postbuckling range under the action of combined compression and shear loads. This research and technology effort was motivated by the need to develop design and life prediction methodologies for such structures. The program has been organized in four tasks. In Task I, Technology Assessment, a complete review of the available test data was conducted to establish the strength, durability, and damage tolerance characteristics of postbuckled metal and composite panels and to identify data gaps that need to be filled. Task II, Data Base Development, was comprised of static and fatigue tests required to fill in the data gaps identified in Task 1. New rigorous static analysis methods aimed at improving the accuracy of the existing analyses and life prediction techniques were developed in Task III. Task IV BUCKLING, COMBINED LOADS, COMPOSITE PANELS, COMPRESSION, CURVED PANELS, DESIGN, DURABILITY, DAMAGE TOLERANCE, FATIGUE, IMPACT, METAL PANELS, POSTBUCKLING, REPAIR, SHEAR
