Review on cyclic plasticity of magnesium alloys: Experiments and constitutive models

Abstract

Fatigue analysis has always been a concern in the design and assessment of Mg alloy structure components subjected to cyclic loading, and research on the cyclic plasticity is fundamental to investigate the corresponding fatigue failure. Thus, this work reviews the progress in the cyclic plasticity of Mg alloys. First, the existing macroscopic and microscopic experimental results of Mg alloys are summarized. Then, corresponding macroscopic phenomenological constitutive models and crystal plasticity-based models are reviewed. Finally, some conclusions and recommended topics on the cyclic plasticity of Mg alloys are provided to boost the further development and application of Mg alloys.
