“…Effect of frequency on multi-axial fretting fatigue lives of Al-Zn-Mg alloys can be analyzed from the following three aspects: (1)When frequency is low, multi-axial fretting fatigue lives of Al-Zn-Mg alloy is longer because effect of chemical factors and other environmental factors on multi-axial fretting fatigue lives is large [8]. (2) The low frequency provides more extended time for crack propagation [9]. (3) Difference in frequency of the specimen will result in difference of friction coefficient on the specimen's surface which can lead to change of wear degree and fretting area of contact area of the specimen's surface, so as to change crack initiation and propagation, and further multi-axial fretting fatigue lives of Al-Zn-Mg alloy [10].…”

Abstract. In this paper, effect of frequency on multi-axial fretting fatigue damage behavior of Al-Zn-Mg alloys is studied. Point contact fretting fatigue tests are used to research effect of frequency on multi-axial fretting fatigue lives, fretting wear area and fracture appearance. Based on experimental results of effect of frequency on multi-axial fretting fatigue of Al-Zn-Mg alloys, fretting fatigue damage behavior of Al-Zn-Mg alloys are intensively analyzed. Results showed that there exists serious stress concentration in fretting fatigue damage zone which due to fretting fatigue as the essence of frequency is chemical factors which is related to time. With frequency increases, fretting fatigue lives reduce nonlinearly and then increase in which lies in a break point in that existence of competitive relations between fatigue failure and surface abrasion.
