Original Abstract

In this article, cyclic hardening-softening behaviors of high strength aluminum alloy 7020 in T6 condition are studied. By comparison of cyclic deformation curve and unidirectional curve was found, that there is no significant change in cyclic response on tested material and that material can be accepted as cyclic stable. Experiments in high cycle area no discontinuity between low-cycle and high-cycle area was detected. Presented properties were not influenced by the different loading frequence (5 a 145 Hz) on different testing machines for low and high fatigue area.
