Fatigue, Fracture, and Crack Arrest from Bending Induced Pre-strain in Superelastic Nitinol

The present study evaluates the fatigue and fracture performance of electropolished Nitinol wire apex specimens subjected to a range of initial bending crimp/pre-strains to determine how the fatigue behavior may be modified by compressive strains and residual stress. Three extrados (tensile) crimp/p...
