A Critical Review of the Short Crack Problem in Fatigue

Abstract

Fatigue crack growth rate predictions based on linear elastic fracture mechanics can significantly underestimate the growth rates of smaller cracks. This study was undertaken to assess the significance of this short-crack phenomenon relative to a damage tolerance analysis of turbine engine components. An integrated program of experimentation and analysis was undertaken to identify the crack tip parameters that control fatigue crack growth rates for small cracks. The program began with a detailed critical review of the available literature. This report presents the results of the literature review.
