Analysis of residual stresses around 'dimpled' cold-expanded holes in aluminum alloy plates

Abstract:

A traditional approach to increasing fatigue resistance of many assemblies involves the creation of regions of compressive residual stress. For example, riveting holes used in modern passenger aircraft are currently subjected to cold expansion using split mandrel tools. The method is relatively expensive and not entirely problem-free. In the present study we consider a method of creating residual stresses around drilled holes referred to as 'dimpling', that itself is a variation of a novel te...
