AN EXPERIMENTAL STUDY ON THE MECHANICAL BEHAVIOR OF SUPERELASTIC NITI WIRES
This paper presents an experimental study on the mechanical behavior of superelastic NiTi shape memory alloy (SMA) wires to verity the suitability of superelastic SMA wires as kernel components for seismic protection devices. Cyclic number, strain amplitude and strain rate are considered as test parameters to investigate their effects on the mechanical parameters such as phase transformation stress, energy dissipation per cycle, secant stiffness, equivalent damping ratio and residual strain. The experimental results show that the superior characteristics of superelastic NiTi wires, such as high energy dissipation, large restoring deformation, are suitable for passive vibration control devices in civil engineering.
