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

Abstract

Electric resistance gauges have been used to investigate the strains induced around a pair of closely-spaced interference-fit fasteners (nominal centre distance equalling two hole diameters) in a D6ac steel plate. For comparison, a finite element analysis was performed for the same geometry using the penalty element method. Measured strains showed broad agreement with the results of the finite element analysis and the latter 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. Originator-supplied keywords: Bolted joints; Stress analysis; Finite element analysis; Interference-fit devices; Elasticity; Fasteners.
