(a) CAD model of NiTi specimen for static and fatigue characterization. The significant dimension of gauge length (L), wires width (W) and thickness (Th) are reported. (b) Symmetrical FE model of a tensile test up to 5%: the total maximum strain, uniform and distributed along each wire, is equal to 4.459%, which means that almost the whole load applied to the specimen is transferred on its gauge length.
