Abstract：The mechanical characteristics, constitutive models of Shape Memory Alloys (SMAs) and their applications in different fields are reviewed. Firstly, the material and mechanical properties and the application of SMAs in smart structures are analyzed, and the methods and characteristics of current micro/meso/macroscopic constitutive models to describe the thermodynamic behavior of SMAs are introduced. Secondly, the application status of SMAs in different fields is described in detail, and the application of structure optimization technology in improving the properties of smart structures is particularly summarized, and the problems existing in current research of SMAs are analyzed. Finally, the key technologies and in the future development of SMAs based smart structures are discussed.
