Material Selection Procedures for Advanced Transport Aircraft

This paper will discuss the procedures used for material selection that were developed and used for two Advanced Metallic Structures, Advanced Development Programs (AMS/ADP) sponsored by the Air Force Flight Dynamics Laboratory (AFFDL) under joint management and direction of AFFDL and the Air Force Materials Laboratory, Wright-Patterson Air Force Base, Ohio. The relationship of structural properties and the role of fracture mechanics in material selection are covered. The application of the selection criteria is demonstrated as it was applied to the Advanced Metallic Air Vehicle Structure.
