Abstract
Vibration control of engineering structures and reducing its unpleasant effects such as high cycle fatigue (HCF), structural failure, noise and etc., has been a very active subject of research. Although reducing weight of structures can be counted as a positive achievement, it may lead to increase in vibratory motions. Energy dissipation due to high amount of hysteresis in shape memory alloy (SMA) wires which is vibrating together with the structure, is a potential solution in vibration control field. In this regard, reducing vibration amplitude is obtained along with relatively low increase in weight of structure respect to other dampening methods like viscoelastic materials. In this paper, carried out experimental tests on Ni-rich Nitinol samples are presented and required parameters for simulation of the pseudo-elastic behavior are extracted. These tests involve calorimetry and various tensile tests using environmental chamber. Pseudo-elasticity, pseudo-plasticity, strain recovery and de-twinning phenomena are perceived experimentally. Also, response of a Nitinol wire by considering its pseudo-elastic behavior is presented numerically.

Highlights
  • It is possible to reduce vibrations of an engineering structure without applying too much weight to it by employing the pseudo-elastic property of shape memory alloys.
  • The presented results could be used in numerical analyses and phenomenological models for simulating the pseudo-elastic behavior of shape memory alloys.
