A fatigue multi-site cracks model using coalescence, short and long crack growth laws, for anodized aluminum alloys [PDF]
, 2010 It has been shown that decrease of the fatigue life of aluminium alloys treated with anodization can be explained by the degradation of surface condition due to pickling.

A probabilistic high cycle fatigue model applied to cast Al-Si alloys [PDF]
, 2013 In this work, the high cycle fatigue behavior of cast hypo-eutectic Al-Si alloys is investigated. It is observed that two different coexisting fatigue initiation mechanisms can occur in these materials depending on the presence of different ...
