New Advances of Research on Constitutive Models of Shape Memory Alloy

In order to promote the development and engineering application of constitutive model of shape memory alloy, summarization is made on the current development situation of the model. The theoretical basis, application range as well as the advantages and disadvantages of the models which have strong influence are analyzed and compared with each other. The author has proposed the constitutive model of recovery force of SMA under complete restrained condition. Some suggestions for further extensions of the models are given here.
