Differences in the response to in-phase and out-of-phase multiaxial high-cycle fatigue loading

Popis výsledku v původním jazyce

This paper discusses the phase shift effect occurring between two and more load channels of multiaxially loaded specimens. The discussion concludes that there is an extreme shortage of good experimental data that would prove the existence and the trend of the phase shift effect in the high-cycle fatigue region. It is no wonder that there are so many fatigue strength estimation criteria that use quite different computational concepts, because the response to the phase shift effect in the experimental base is often hidden in a conglomeration of other interacting effects. The paper presents results of a sensitivity study that compares the fatigue strength estimation results for various such criteria for the same stress amplitudes, but for different phase shifts between the push-pull and torsion load channels. These results show that, with the exception of criteria that assume a zero phase shift effect, the phase shift affects the results of each studied fatigue strength estimation criterion in a different way. A proposal for an experimental setup that would show the real trend unambiguously, and that would enable researchers to check the multiaxial fatigue strength criteria is provided in the paper.
