This report is Vol. IV of a 6-part final report. Extensive experiments were conducted as a part of the assessment of damage tolerance of aircraft attachment lugs. Experimental results and the correlations with analytical predictions using the analysis methods developed under this contract were reported in Vol. III of the final report. In this volume, all the experimental test data generated are tabulated. The experiments were divided into two groups Group I and Group II. Group I consists of only simple straight shank male lugs and Group II consists of lug configuration commonly used in design practices such as tapered, dogbone, clevis and real aircraft lugs. This volume contains the tabulation of raw residual strength and fatigue crack growth data for both groups of tests. This volume also contains the baseline material property data, crack initiation test results and details of different loading spectra used in testing. Originator supplied keywords include Attachment lugs, Aircraft, Damage Tolerance, Experimental testing, Data tabulation, Crack initiation, Propagation, Residual strength, Through-the-thickness, Corner, Analysis, Correlation, Constant-amplitude, Block spectrum loading, Flight-by- flight spectrum loading, symmetric and Off-axis loading, Interference-fit bushing, Lower thick ness, Straight lugs, and Tapered lugs, Dogbone lugs, Clevis lugs, Thick lugs, Real lugs.
