The macroscopic behavior of Nickel Titanium Shape Memory Alloy (SMA) wires suffers from hysteresis. This is related to the fraction of material that is in detwinned martensite crystallographic orientation. In this work, a novel physical model is proposed that describes the fraction of transformed material on a macroscopic level. The model is history-free, and hence, is ideal to implement in model-based control strategies.
