Study on Hysteretic Energy Dissipation of SMA Wires, Bars and Plates

Abstract:

Through tensile tests of shape memory alloy(SMA) wires, bars and plates, this paper analyzes hysteretic energy-dissipating capacities of these smart SMA materials in cyclic loading conditions. According to the test results, this article demonstrates the influence on energy dissipating capacity of SMA wires, bars and plates by different strain amplitudes, loading frequencies, cyclic numbers and pre-strains, then obtains change rules of hysteretic energy-dissipation. The test results show that the SMA wires is better than the other two SMA bars and plates, the SMA wires, bars and plates had better to be training before civil engineering application.
