Abstract:

7075-T7351 and 7075-T7651 aluminum plates of varying thicknesses were mechanically tested to verify certain design allowables used in the initial B-1 design. For the 7075-T7351 alloy, tensile and compressive strengths decreased slightly with increasing plate thickness. 7075-T7351 shear strengths increased very slightly with increased plate thickness. Bearing strengths varied noticeably with plate thickness, therefore requiring two data sets to characterize design allowables. This variation was at least partially due to different specimen location. For the 7075-T7651 alloy, more test plates of varying thicknesses are needed for a complete statistical analysis.
