Durability Methods Development. Volume 1 - Phase 1 - Summary

Abstract

A summary is presented of an analytical methodology developed to meet USAF durability requirements. Details are given in four companion volumes. Analytical approaches that are currently used or have potential to be used to determine economic life are surveyed. Results of a structural survey of durability problems experienced at USAF ALC's are summarized. Durability critical parts criteria and economic life criteria are discussed. An analytical method to determine the crack population in a structure as a function of service time is presented. Fastener-hole cracking is the basic form of damage analyzed. Representations of initial quality and growth of small cracks are discussed. The effect of inspection and repair on the distribution of cracks is included.
