3. A 15 cm length of 1-mm-diameter SMA wire is loaded and unloaded at room temperaturc. Because of the formation and recovery of stress-induced martensite, the stress-strain diagram from this test exhibits a hysteresis loop. Idealizing this response as elastic-perfectly plastic as shown calculate the energy dissipated during the loading-unloading cycle. σι 112 83 4
