Available in PDF, EPUB and Kindle. Book excerpt: A structural test program of a typical aircraft structural configuration was conducted to assess the current Air Force damage tolerance design requirements defined in MIL-A-83444. The specimens, made of 2024-T3XX and 7075-T6XX, were subjected to randomized flight-by-flight spectra, representative of fighter/trainer and bomber/cargo-type loading spectra, respectively, and to constant amplitude loading spectrum. A total of 72 specimens were tested. The test results were correlated with analytical predictions using the crack growth method and combined method. As a result of this study, a recommendation is provided to the validity of MIL-A-83444, to develop guidelines for selection of critical crack locations, and to assess the state-of-the-art analytical capabilities in predicting crack growth and crack initiation time. This volume, Volume I of a five-volume report, presents an Executive Summary of the entire program.

Book excerpt: This is the 5th volume of a 6 part report on a program to develop the design criteria and analytical methods necessary to ensure the damage tolerance of aircraft attachment lugs. This program consisted of seven tasks proceeding from and extensive cracking data survey and assessment of nondestructive inspection capabilities (NDI), through analysis methods development and evaluation, to the recommending of the damage tolerance design criteria for aircraft attachment lugs. Volume I-IV provide: Results of the crackling data survey and nondestructive inspection capabilities assessment (Tasks I and II); The developed analytical methods for predicting residual strength and crack growth behavior in attachment lugs; The results of analytical predictions (Task IV), experimental testing (Task V) and analytical-experimental correlations (Task VI); and The tabulation of raw experimental data generated under Task V. The volume summarizes results for the first six tasks and recommends the initial flaw requirements for damage tolerance design criteria for aircraft attachment lugs, which were developed in Task VII. Vol VI is the user's manual for the computer program 'LUGRO' for the prediction of crack growth behavior in attachment lugs.

Book excerpt: Analysis procedures for the assessment of the damage tolerance of aircraft attachment lugs are developed and presented. Stress and fracture analyses are conducted for simple male straight shank lugs subjected to symmetric loading and tapered lugs subjected to symmetric and off-axis lodings. Solutions of stress distributions and stress intensity factors are obtained for various parameters. The parametric variations include lug outer-to-inner radius ratios corner and through-the-thickness cracks, crack lengths and aspect ratios, with and without interference-fit bushing and loads above and below yield of the lugs. Methods of varying degree of sophistication are considered in the development of stress intensity factor solutions for cracks in attachment lugs. For through-the-thickness crack problems, simple compounding method, two- dimensional cracked finite element method, and the weight function mthod are used. In the case of corner cracks, solutions are obtained using simple compounding method, weight function method and rigorous three-dimensional hybrid displacement cracked finite element method. The stress distributions and the stress intensity factors are consolidated into a crack growth analysis procedure including several crack growth models and spectrum retardation models to predict the fracture and crack growth behaviors in attachment lugs.
