Book excerpt: To evaluate the potential of friction stir welding (FSW) as a replacement for traditional rivet fastening for launch vehicle dry bay construction, a large-scale friction stir welded 2090-T83 aluminum-lithium (Al-Li) alloy skin-stiffener panel was designed and fabricated by Lockheed-Martin Space Systems Company - Michoud Operations (LMSS) as part of NASA Space Act Agreement (SAA) 446. The friction stir welded panel and a conventional riveted panel were tested to failure in compression at the NASA Langley Research Center (LaRC). The present paper describes the compression test results, stress analysis, and associated failure behavior of these panels. The test results provide useful data to support future optimization of FSW processes and structural design configurations for launch vehicle dry bay structures.Hoffman, Eric K. and Hafley, Robert A. and Wagner, John A. and Jegley, Dawn C. and Pecquet, Robert W. and Blum, Celia M. and Arbegast, William J.Langley Research CenterFRICTION STIR WELDING; LAUNCH VEHICLES; SKIN (STRUCTURAL MEMBER); COMPRESSION TESTS; STRESS ANALYSIS; SPACECRAFT CONSTRUCTION MATERIALS; FABRICATION; RIVETING; ALUMINUM-LITHIUM ALLOYS
