    The properties of SMA (Shape Memory Alloys, smart materials) are associated to a first order phase transition named martensitic transformation that occurs between metastable phases: austenite and martensite. At higher ...
  • The SMA properties in civil engineering applications. The SMARTeR project: use of SMA in damping of stayed cables for bridges 

    Torra Ferré, Vicenç; Isalgué Buxeda, Antonio; Carreras, G.; Lovey, Francisco Carlos; Soul, H.; Terriault, P.; Zapico, B. (2009-09)
    Conference lecture
    Open Access
    Abstract. One of the classical applications of the SMA is based on the used of the hysteresis cycle associated to the martensitic transformation (classically, described as a first order phase transition) for damping ...
