USAF Durability Design Handbook: Guidelines for the Analysis and Design of Durable Aircraft Structures.

Abstract : This is the first edition of the Durability Design Handbook. Objectives of the handbook are: (1) summarize and interpret the essential U.s. Air Force Durability Design requirements for metallic airframes, (2) provide durability analysis criteria for economic life and durability critical parts, (3) provide state-of-the-art durability analysis concepts and methods for quantifying the extent of damage for a population of details (e.g., fastener holes, fillets, cutouts, lugs, etc.) as a function of time, (4) provide guidelines and design data for implementing the durability methodology and for assisting contractor and USAF personnel in complying with the intent of the durability specifications for metallic airframes. This document, loosely called a Handbook, provides guidelines, concepts, analytical tools and the framework for incorporating future durability methodology advancements and design data.
