Low-Cycle Fatigue of Structural Alloys in Relation to Their Plasticity

Abstract

A study was made of the low-cycle fatigue life of martensitic steel EI-961F, EI-961, SN3, SN2A, VNS-2, chromium-nickle steels EI-696M, EI-835, nickel alloy VKh-101, copper alloy BrKhO-8, and aluminum AK-4. The fatigue tests were made with smooth and notched samples. For notched samples, relations between stress and number of cycles are presented. No such relations for unnotched samples could be found. The mechanism of the low cycle fatigue rupture is discussed.
