Abstract
In this paper is investigated the torsion and rotating bending fatigue endurance of AISI 6063-T5 aluminum alloy. Special attention was devoted to fatigue endurance reduction under torsion fatigue testing on this material. A torsion fatigue machine has been developed in our laboratory, which is under patent consideration. Torsion fatigue tests were carried out at frequency of 10 Hz and load ratio R = 0; whereas rotating bending fatigue tests were at 50 Hz and R = - 1. Results reveal a noticeable fatigue endurance reduction under torsion, compared to rotating bending loading. Fatigue life and crack propagation were analyzed for both fatigue testing modalities.
