WebAfter testing NiTi SMA wires with different diameters, lengths and loading forces and studying the mechanical behaviour of the energy storage ejection, the energy storage ejection law of superelastic SMA wire is defined. Moreover, indicators such as resistance change rate, stress, strain and energy conversion efficiency are also tested and ... WebNov 7, 2024 · From the results, it can be seen that the SMA wire was able to produce contraction of 3 mm at temperature of 55 °C with force measurement of 20 N. The resistance was found to be 1.37Ohm at ambient temperature. In order to produce 2 mm displacement, the SMA wire has to be heated to 47 °C.
