An idealized superelastic model under uniaxial loading.
(a) Comparison between an elastic indentation curve and a superelastic indentation curve, and (b) definitions of the bifurcating point and the corresponding bifurcation force and the returning point and the corresponding return force .
Relationships between the normalized bifurcation force and the normalized forward transformation stress and between the normalized return force and the normalized reverse transformation stress for under small deformation condition.
(a) Determination of the bifurcating point from the elastic slope and superelastic slope curves for the loading process, and (b) determination of the returning point from the elastic slope and superelastic slope curves for the unloading process.
