A New Continuous Model of Shape Memory Alloys
In this paper a new one-dimensional continuous model was proposed for Shape Memory Alloys (SMAs), which can be applied in the continuous dynamic loading system.After a literature review over the constitutive modeling of SMAs, an improved continuous model considering the influences of the various strain rates of SMAs was developed, which based on a series of experiments.The results of the experiments were used to validate the effectiveness of the proposed model.The constant factors in the model were determined according to the measured experimental data.The parameters in the model were also numerically analyzed and the numerical results matched well with experimental results.The results of the simulation showed that the developed model can effectively represented the relationship between the strain and stress of SMAs under dynamic loading and can be better applied in structure control.
