Improving the design and performance of medical stents for implantation in the human body is of current interest. This paper describes a study of fatigue-crack propagation behavior in the superelastic alloy Nitinol. Specifically, the objective of this work was to study the effect of environment on c

Medical devices, particularly endovascular stents, manufactured from superelastic Nitinol, a near-equiatomic alloy of Ni and Ti, are subjected to complex mixed-mode loading conditions in vivo, including axial tension and compression, radial compression, pulsatile, bending and torsion. Fatigue lifeti
## Abstract Several key fracture‐mechanics parameters associated with the onset of subcritical and critical cracking, specifically the fracture toughness, crack‐resistance curve, and fatigue threshold, have recently been reported for the superelastic alloy Nitinol, in the product form of the thin‐w
