Abstract: This paper regards some characteristics of the standard hysteresis cycle of SMA when used to supply damping in Civil Engineering applications. The mechanical efficiency (ratio between the dissipated energy again the elestic contribution) increases when the starting point is situated in parent parent phase or inside the hysteresis cycle. In general the metastable or diffusion effects in parent phase and in coexistence (in static and also in dynamic conditions) remain not well quantified or completely known in SMA.
