| Abstract: | Shape memory alloys(SMA) are a class of novel functional materials used as both actuators and sensors.Due to unique thermomechanical behaviors such as shape memory effect(SME),superelasticity and high damping property,et al,they are perfect candidates for structural vibration control in civil engineering.This paper presents a study of the dynamic behavior and strain-rate-dependent constitutive model of superelastic NiTi SMA wires.Cyclic tensile tests on NiTi SMA wires at different stain rates were carried o... |
