Here you can download the code to simulate a one-degree-of-freedom rotary system. The systems is explained in details in Elahinia, M. and Ashrafiuon, H., “Nonlinear control of a shape memory alloy actuated manipulator,” Journal of Vibration & Acoustics – Transactions of the ASME, October 2002, 124(4): 566-575. Please copy the Simulink file and the two MATLAB files in the same directory. There is also a Mathematica code developed by Frnacesco Bucchi for simulating shape memory and superelastic behavior The details of this modle are explained in Bucchi, F. Elahinia, M. Forte, P. And Frendo, F., “A passive magneto-thermo-mechanical coupling actuatedby SMA springs and MR fluid”, International Journal of Structural Stability and Dynamics, October 2014, 14(8): 1440031 DOI: 10.1142/S0219455414400318.
