Study on Strain-Sense Property of TiNi and TiNiCu Shape Memory Alloys
Concerning important infrastructures and civil structures, they need real time detection during the service, such as high-rise buildings, cables, bridges and dams. Therefore, it is necessary to study sensing property of shape memory alloy (SMA) for developing a sensing element embedded in the structures to carry out damage detection. In this paper, change rate of resistance-stress-strain relationship of TiNi and TiNiCu shape memory alloys (SMAs) under elongation is examined. Tests are conducted in MTS at room temperature for the mechanical and strain-sense properties. According to the test results, it is concluded that TiNi and TiNiCu in martensitic phase and austenitic TiNi SMA wires have good strain-sense property. The change rate of resistance of SMA wires has a linear relation with the applied strain. Additionally, stress-strain relation is also predicted by Brinson Model. This study is devoted to sensing properties of TiNi and TiNiCu shape memory alloy.
