Abstract

In our previous paper [1], a constitutive model was developed for the stress-induced martensitic transformation and reorientation in single crystalline shape memory alloys. The critical condition and evolution equation for the phase transformation and reorientation were proposed. In this paper, the model proposed in our previous paper [1] is applied to simulate the behavior of stress-induced phase transformation in a CuZnAl single crystal and reorientation between CuAlNi martensite lattice correspondence variants. It is found out that the prediction results are consistent with the experimental data reported in the literature.
