Obiettivo del progetto (Objective)
'SMyle involves mathematical modell ing, design, fabrication and testing of a Shape Memory Alloy coupon undergoing actuated controllrd deformation. It is envisaged that two different SM actuating principles will be pursued. In the first approach the actuator will be embedded in the coupon in the form of an active layer whereas in the second approach the use of the so called compliant mechanisms will be investgated with the SMA wires as actuating elements. Work will be carried out as following: Determination of single-cycle/multi-cycle loading conditions which involve the thermal-mechanical and electrical aspects, with empasis on hysteresis, as well as determination of experimental conditions, i.e. surface uniform- & non-uniform actuation type of loading; prediction of specimen's surface response by means of simple analytic methods. Uniform as well non uniform surfaces of the same SMA specimen will be pursued. Testing will include the deformation to the desired shapes repeatedly and measure reproducibility and attainment of desired shape. The effect of temperature will also be evaluated by completing several actuation cycles at temperatures near the SMA transformation temperature. Commercially available SMA will be used and an initial characrerization phase is foreseen. The aim is to have the material behaviour under static and dynamic conditions up to failure. It is foreseen that for every actuating principle the most promising concepts will be bench-tested to evaluate characteristics and highlight challenges. Up to four concepts will be tested in this context. Eventual modification of numerical model and structural correction of the SMA specimen in case of unsatisfactory experimental outcome will be carried out. Finally, a functional SMA specimen and recommendations for future work will be delivered.'
