Physical and numerical aspects of a novel rate-independent three-dimensional macroscopic model for NiTi shape memory alloys were presented. The model was successfully tested through simulations of a NiTi textured wire subjected to complex thermal and mechanical loadings. Simulations presented in this contribution also showed high influence of anisotropy and R-phase on the performance of NiTi components in general loading modes.
