Annotation	In this work, a constitutive model tailored for nonproportional multi-axial loading of NiTi SMA exhibiting two-stage phase transformation via R-phase is enhanced so that the anisotropy of martensitic structure is captured. Numerical simulations of the mechanical response of a NiTi SMA helical spring subjected to thermal cycling at a constant applied force are performed and compared with experimental data. Simulations provide detailed information on the evolution of distributions of phase fractions and stress within a cross-section of the wire forming the spring.
