Sma wire testing
WebMay 1, 2024 · 1. Introduction. Shape memory alloys (SMAs) are a class of active materials that can perform reversible actuation upon thermomechanical training [1].Although SMAs are manufactured in a variety of shapes, including plates, springs, wires, and ribbons, the most widely used shape is the one-dimensional SMA wire, which can be integrated into … WebMar 23, 2024 · Table 1 Material parameters of SMA wire Full size table In order to stabilize the mechanical behaviour of SMA wires, mechanical training through cyclic loading and unloading was carried out before the test. When the applied strain of SMA wires reaches 6%, the residual strain is negligible, as shown in Fig. 5.

The typical stress-strain curve of the SMA monofilament wire is illustrated in figure 1, where the ends of the SMA wire were clamped by flat wedge grips during the tests. A typical flag-shaped response with satisfactory recoverability can be seen.
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. Webwww-personal.umich.edu
