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.
