Abstract : Most medical applications involving superelastic Ni-Ti shape memory alloys are based on thin wires or tubes. If the tensile behavior of such specimens has been extensively described in the literature, only few studies deal with their mechanical behavior under pure bending and compressive load 1. In this paper, Ni-Ti wire behaviors were experimentally investigated using pure bending and uni-axial tensile experiments. Uniform or localized behaviors were observed depending on the thermo-mechanical treatment of the wire. Theoretical bending model was proposed. For nonlocalized tests, it allowed to analyze tension-compression asymmetry. Tension and compression constitutive equations were proposed to model localization in bending.
