The fatigue behaviour of a typical joint configuration, available in two variants, has been investigated, assessing also the influence of various treatments. Different batches of specimens were evaluated: basic material, Tartaric Sulphuric Acid anodized and also coupons subjected to fatigue enhancement processes, such as Cold eXpansion and Laser Shock Peening.
