Cold working of holes in metal joints is frequently used to improve the fatigue and damage tolerance properties of aeronautical structures. How would its effectiveness change for a hole which conditions have departed from the nominal? This scenario is often found during aircraft structural modifications or major repairs and its effect is quantified in this study using theoretical and XFEM solutions correlated with test results.
