Rotary-bending fatigue characteristics of medical-grade Nitinol wire.
The rotary bending fatigue properties of medical-grade Nitinol wires were investigated under conditions of 0.5-10% strain amplitudes to a maximum of 10(7) cycles. The results from this study provide insight into the behavior of Nitinol under fully reversed (εmin/εmax=-1) fatigue conditions for three compositions, two surface conditions and three test temperatures. For pseudoelastic conditions t...
متن کاملFatigue testing of controlled memory wire nickel-titanium rotary instruments.
INTRODUCTION To improve the fracture resistance of nickel-titanium (NiTi) files, manufacturers have introduced new alloys to manufacture NiTi files and developed new manufacturing processes. This study was aimed to examine the fatigue behavior of NiTi instruments from a novel controlled memory NiTi wire (CM Wire). METHODS Instruments of ProFile, Typhoon (TYP), Typhoon CM (TYP CM), DS-SS025042...
متن کاملCharacterizing Fatigue and Fracture Response of Medical Grade Nickel-Titanium Alloys by Rotary Beam Testing
With respect to a dynamic test protocol, fatigue information has been reliable in predicting wire wear longevity as well as critical structural integrity. It has been noted that the efficacy of modern medical devices are confined by the life cycle of the material of which they are composed. The aim of this study is to expound on the means of how rotary beam fatigue test methods merit attention ...
متن کاملCharacterizing Fatigue Response of Nickel-Titanium Alloys by Rotary Beam Testing
Fatigue information has been reliable in predicting wire critical structural integrity. The aim of this study is to expound on the characterization technique of rotary beam fatigue testing RBT . By alternating tension and compression stress states through RBT, it is possible to determine the life expectancy of Nitinol monofilament round wires. Fatigue testing has been employed to characterize t...
متن کاملAuto-Gopher - a wire-line rotary-hammer ultrasonic drill
Developing technologies that would enable NASA to sample rock, soil, and ice by coring, drilling or abrading at a significant depth is of great importance for a large number of in-situ exploration missions as well as for earth applications. Proven techniques to sample Mars subsurface will be critical for future NASA astrobiology missions that will search for records of past and present life on ...
