Stresses and Strains in a Plate Resulting from Two Closely-Spaced Interference-Fit Fasteners

摘要

Electric resistance gauges were used to investigate the strains induced around a pair of closely-spaced interference-fit fasteners (nominal center distance equalling two hole diameters) in a D6ac steel plate. A finite element analysis was performed for the same geometry using the penalty element method. Measured strains show broad agreement with the results of the finite element analysis and it is indicated that the peak stress level in the plate at the hole circumference would be 1.14 times the level for a single similar interference-fit fastener in an infinite plate.
