Abstract
A shape memory alloy (SMA) spring system is analysed to determine its response to harmonic forcing. In particular, the superelasticity effect of the system is investigated. The shape memory alloy is modelled using a piecewise linear force–displacement curve. The SMA spring is arranged so as to introduce a geometric nonlinearity. The system of equations are numerically integrated and frequency response curves are determined. Periodic, quasiperiodic and chaotic motions are observed for different combinations of parameter values.
