Project Description:
o
Shape Memory Alloys (SMA) have peculiar properties which are all connected to the solid-solid phase transformation between austenite (stable at high temperature) and martensite (stable at low temperature). Concerning applications in structural engineering, some interesting features of SMA are the possibility of dissipating large amounts of energy and, via appropriate thermal treatments,the capacity of undergoing large strain cycles without residual deformation. Experimental evidence points out that these materials have good fatigue resistance and great reliability in the long run. Thanks to all these properties, SMA have the potential to be used in structural design as a smart material able to mitigate the effects of transient loading. The proposed Project builds on these ideas to develop methodologies and associated tools for the optimal design of SMA dampers fitted for applications in civil engineering. The domain covered by the Project ranges from theoretical study of material models to large-scale experiments. The Project brings together scientists who are leaders in their respective specialities. Thanks to the combined expertise of the participants, the Project has reasonable chance to make a breakthrough in the area of SMA and their application in civil-engineering.
