Journal ArticleDOI
Experimental and theoretical investigation of the frequency effect on low cycle fatigue of shape memory alloys
Yahui Zhang,Yahui Zhang,Yajun You,Ziad Moumni,Ziad Moumni,Gunay Anlas,Jihong Zhu,Weihong Zhang +7 more
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
Multiscale TRIP-based investigation of low-cycle fatigue of polycrystalline NiTi shape memory alloys
Yahui Zhang,Yahui Zhang,Ziad Moumni,Ziad Moumni,Yajun You,Weihong Zhang,Jihong Zhu,Gunay Anlas +7 more
TL;DR: In this paper, a multiscale investigation of fatigue crack initiation in shape memory alloys (SMAs) based on Transformation Induced Plasticity (TRIP) is presented, and a mechanism for fatigue crack induction during cyclic stress-induced phase transformation along with theoretical model is proposed.
Journal ArticleDOI
Energy-based fatigue model for shape memory alloys including thermomechanical coupling
TL;DR: In this article, a low cycle fatigue criterion for pseudoelastic shape memory alloys was developed to take into account thermomechanical coupling, and the fatigue cracks initiate when the stored energy inside the material reaches a critical value.
Journal ArticleDOI
Effect of the amplitude of the training stress on the fatigue lifetime of NiTi shape memory alloys
TL;DR: In this article, a mechanical training process that allows enhancing resistance to low cycle fatigue of shape memory alloys was presented, and three training stresses were tested (0−509.6, 0−637.3, and 0−764.3).
Journal ArticleDOI
Comparative investigation of the fatigue limit of additive-manufactured and rolled 316 steel based on self-heating approach
TL;DR: In this article, a series of tensile cycling experiments are carried out on AM 316 steel specimens; temperature variation resulting from the self-heating phenomenon is recorded by an infrared thermography (IR) camera and fatigue limit is deduced.
