Abstract

Abstract

A new constitutive model of shape memory alloys (SMAs) based on Tanaka's martensite fraction exponential expression is produced. This new model can present recoverable shape memory strain during different phase transformation, and reflect the action of martensite reorientation. Also it can overcome the defect of Tanaka's Model when the SMAs. microstructure is fully martensite. The model is very simple and suitable for using, and the correct behavior of the model is proved by test.
- shape memory,
- constitutive model,
- pseudoelasticity
