Abstract
The goal of this research activity is to evaluate the capability of Laser Shock Peening (LSP) technology to improve fatigue life in open-hole aluminium specimens. Thin, dog-bone specimens were LSP treated in direct ablation mode and subsequently tested. The obtained results have not proven the advantage of LSP technology over traditional residual stress insertion techniques around openholes, such as cold working. Therefore, the focus of the activity was moved towards understanding the causes of the observed fatigue life reduction.
