    Abstract

    This paper presents the methodology and findings of the experimental research carried out
    on
    small diameter Nitinol wires at Newcas
    tle
    University. Among all compositions of Shape memory alloys (SMA), Nitinol is
    understood
    to be the most suited for use in the design of building and
    bridge structures subjected to earthquake loading conditions. The shape memory
    effect
    and
    superelasticity
    demonstrated by Nitinol lends to higher
    energy dissipation capability of this alloy and hence is suited for cyclic dynamic loading conditions. A series of static and
    cyclic dynamic tests were
    developed and conducted on Nitinol wires of 1mm, 0.5mm and 0.25
    mm
    diameters
    to assess their
    basic
    mechanical properties and
    energy dissipation
    capabilities. The results from these experiments agree with the trends suggested in the literature and show that smaller or t
    hinner the diameter of a
    Nitinol
    wire greater is it
    s energy dissipating capability.
