Abstract:
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 users manual for the computer program LUGRO for the prediction of crack growth behavior in attachment lugs.
