Fatigue analysis of shape memory alloys: energy approach
TL;DR: In this article, a low cycle fatigue criterion for NiTi shape memory alloys (SMAs) is defined in order to perform numerical calculations necessary for designing structures made of SMA and subjected to cyclic loading.
Journal ArticleDOI
Effects of grain size on tensile fatigue life of nanostructured NiTi shape memory alloy
TL;DR: In this article, the effects of grain size (GS) on tensile fatigue life of nanostructured NiTi superelastic shape memory alloys (SMAs) with GS = 10nm, 42nm and 80nm were investigated.
Journal ArticleDOI

TL;DR: In this article, the effect of cyclic loading frequency on pseudoelastic behavior and low cycle fatigue of shape memory alloys (SMAs) is investigated, and a new strain energy based fatigue model is proposed, and validated by experiments performed under different load ratios.
Journal ArticleDOI
Investigation on fatigue behaviors of NiTi polycrystalline strips under stress-controlled tension via in-situ macro-band observation
TL;DR: In this paper, the authors conducted systematic experiments on NiTi polycrystalline strips under stress-controlled cyclic tensile loadings with in-situ optical observation on the Luders-band evolution and found that applied stress level and frequency influence the band formation changing the material's fatigue behaviors significantly.
