Fatigue life prediction of aluminium profiles for mechanical engineering

Tomasz Tomaszewski, Janusz Sempruch
The study presents a method to determine the a −N curve (high cycle fatigue) for profiles
made of AW-6063 T6 aluminium alloy. Experimental material data for a mini specimen
taken directly from the tested item and selected empirical correlations allowing for a size
effect have been used. A model yielding the lowest relative error of estimating the fatigue
life is presented.
