Tips and Tricks for Characterizing Shape Memory Alloy Wire: Part 2—fundamental Isothermal Responses
T his is the second in a series of articles to introduce phenomena and experimental subtleties that can lead to difficulties in testing shape memory alloy (SMA) wire. Our aims were to acquaint uninitiated engineers with SMA testing and to highlight pitfalls in technique and interpreting test results. In the previous article (Part 1), thermomechanical experiments were presented on two commercial...
متن کاملFabrication of Spiral Stent with Superelastic/ Shape Memory Nitinol Alloy for Femoral Vessel
Stent is a metal mesh tube for opening the obstructed vessels of the body. Ni-Ti alloy is a suitable metal for fabrication of stent due to its potential for applying the appropriate stress and strain to the vessel walls. In this study, super-elastic Nitinol wire was used to build stent samples usable to open femoral vessel. Ageing was performed at 500°C for different periods of time to determin...
متن کاملFinite element analysis of superelastic, large deformation behavior of shape memory alloy helical springs
Brinson’s one-dimensional constitutive modeling for shape memory alloy (SMA) is extended to consider the asymmetric tensile and compressive behavior as well as the torsional behavior. The incremental finite element method using linear Timoshenko beam elements is formulated by the total Lagrangian approach for the superelastic, large deformation analysis of SMA helical springs. The NiTi helical ...
متن کاملFatigue-Crack Growth Behavior in the Superelastic and Shape-Memory Alloy Nitinol
This article presents a study of fatigue-crack propagation behavior in Nitinol, a 50Ni-50Ti (at. pct) superelastic/shape-memory alloy, with particular emphasis on the effect of the stress-induced martensitic transformation on crack-growth resistance. Specifically, fatigue-crack growth was characterized in stable austenite (at 120 8C), superelastic austenite (at 37 8C), and martensite (at 265 8C...
متن کاملFinite Element Modeling of Magneto-superelastic Behavior of Ferromagnetic Shape Memory Alloy Helical Springs
The previous study by thefor the finite element analysis of superelastic, large deformation behaviors of one-dimensional shape memory alloy (SMA) devices is extended to the magneto-superelastic analysis of ferromagnetic shape memory alloy (FSMA) devices. The commercial code ANSYS/ Emag for magnetic analysis is combined with the SMA superelastic analysis program developed by the authors. The num...
