    Influence of stress concentration on the recovery stress generation

    No full text
    The present communication focuses on a numerical and experimental study of the influence of stress concentration on the overall SMA behavior in case of low cycle actuation, more particularly on the recovery stress generation. The results obtained using commercial ANSYS FEM software are compared with experimental recovery stress data registered upon heating of constrained NiTi ribbon specimens with stress raisers of different geometry
