Phenomenological model on thermo-mechanical response of shape memory alloy (SMA) strip is presented in this paper. Thermal response and transformation accompanied deformation are described by the proposed model. Newly transformation expansion tensor is defined to describe the relationship between the transformation-induced deformation of the strip and the temperature. The model is then implemented into ABAQUS by using the user-defined subroutine. Finally, the proposed model is verified by the comparison between the finite element simulation and experiment.
