摘要

Fatigue life enhancement systems such as interference-fit fasteners and cold-expanded holes, are assuming increasing importance for aircraft structures. In this report we formulate a penalty finite-element method for the stress analysis of these common fatigue life enhancement systems. The method is demonstrated by considering two illustrative examples under elastic, plane-stress conditions. The three-dimensional analysis of a uniformly pressurized hole in a plate is also discussed with reference to cold-expanded holes.
