The theory of thin wires developed in  is adapted to phase transforming materials with large elastic moduli in the sense discussed in . The result is a one-dimensional constitutive model for shape memory wires, characterized by a small number of material constants. The model is used to analyze self-accommodated and detwinned microstructures and to study superelasticity. It also turns out that the model successfully reproduces the behavior of shape memory wires in experiments of restrained recovery [22-24], [26-28]. In particular, the model is able to predict the shift to higher transformation temperatures on heating. The model also captures the effect of pre-straining on the evolution of the recovery stress and of the martensite volume fraction.
