Small Crack Growth at Pin Loaded Holes

Abstract

This report describes the results of an experimental study conducted to verify analytical methods for small crack growth prediction at pin-loaded holes under varying load transfer rates. The study was conducted on 2024-T3 joint specimens with an initial 0.003-inch radial thru crack under constant amplitude cyclic and spectrum loads. The test specimens were joined using three different types of doublers. Crack growth data in the small crack regime and the long crack regime was developed. Strain data on doubler plates during testing was obtained.
