Development of Fatigue Test Standards and Mechanical Property Data on Interference Fit Fastener Systems

Abstract

A multiple task program was conducted aiding the establishment of proposed test No. 21, Shear Joint Fatigue Test Specification, of MIL-STD-1312 Fastener Test Methods, and to generate joint fatigue data utilizing two commonly used fatigue rated fastener systems, the Hi Lok/Hi Tigue and Taper Lok. Fatigue testing of 1008 elemental joints considered high, medium, and low load transfer joints. Six important fastener system variables were investigated consisting of fastener configuration, fastener material, amount of interference fit, faying surface treatment, sheet thickness/fastener diameter ratio, and fastener hole fabrication methods. Tests were also conducted to investigate effect on fatigue characteristics due to loading frequency, type of test machine, and specimen fixturing.
