According to the S3T-RoundRobin eﬀort, this paper presents the main results obtained using the SMA model developed by Chemisky et al. , from the calibration to the prediction results. This model is based on thermodynamics of the irrevesible processes. Three internal variables are used to model the macroscopic behavior of SMAs. Parameters identiﬁcation procedure requires only a limited set of experimental data. Comparison between modeling and experimental results are presented for the four data sets of this RoundRobin. Finite Element Analysis was performed to capture tension-torsion tests. Major discrepancies are related to strain localization eﬀects and R-phase transformation which are not included in the present model.
