Advanced Durability Analysis. Volume 4. Executive Summary

Abstract

This report is volume IV of a 5-volume final report on the work conducted under AF contract F33615-84-C-3208. The objectives of this program were to:(1) recommend improvements to the current Air Force durability design requirements(i.e., MIL-A-8866B and MIL-A-87221), (2) develop a probabilistic durability analysis method capable of predicting the durability of advanced metallic aircraft structure for functional impairment such as excessive cracking, fuel leakage and ligament breakage, and (3) update the current Air Force Durability Design Handbook(AFWAL-TR-83-3027). fatigue cracking is the form of degradation considered. This three-phase program consisted of eight tasks. Advanced durability analysis methods were developed and refined under Phase 1. Fatigue test results and fractographic data were acquired and evaluated under Phase 2. Durability, fatigue, equivalent initial flaw size (EIFS),initial fatigue quality (IFQ),time-to-crack initiation (TICI), deterministic and stochastic crack growth.
