Abstract:

NiTi-wire shape memory alloy (SMA) dampers, which utilize NiTi SMA wires to simultaneously damp tension, compression, and torsion, have been developed for structural control implementation in this study. First, three reduced-scale NiTi-wire SMA dampers were constructed. Then, mechanics analysis of the NiTi-wire SMA dampers was performed, based on a model of the SMA-wire restoring force and on tension, compression, and torsion damping analysis. Finally, tension, compression, and torsion experiments were carried out, using the three reduced-scale NiTi-wire SMA dampers of different diameters. The

Abstract:

Ni-Ti-Nb system alloys show wide shape memory hysteresis, suitable for assembly applications. The microstructure is composed by NiTi matrix (with some dissolved Nb) and Nb dispersed particles (with some Ni and Ti content). These particles are to cause the hysteresis widening. This work evaluates the microstructure evolution during wire fabrication process of equiatomic Ni and Ti alloys with increasing Nb content (1.5, 3.0, 6.0 and 9,0%at.). It is shown that as-cast alloys with up to 9% at.Nb and near equiatomic Ni:Ti relation show three main microconstituents: NiTi matrix phase, interdendritic

To evaluate microbial corrosion by weight loss, microbial corrosion and elemental analysis of NiTi and stainless wires after period of 2 months in streptococcus mutans containing media.

Elemental analysis of NiTi wire in streptococcus containing media showed decrease in Ni by 2.9% by weight and Ti decreased 3.07% by weight due to leaching of Ni and Ti from the surface of wires. In stainless steel wire, there was decrease in Fe by 8.82% and Cr 1.39% by weight. Significant microbial corrosion was observed

The use of SMAs in MEMS has so far been limited, partially due to a lack of cost efficient an

Abstract Nitinol (NiTi) shape memory alloy exhibits excellent characteristics for use in biomedical engineering. The material has excellent biocompatibility, corrosion resistance, and wear characteristics, which has increased its use in biomedical applications, including stents and guidewires. While NiTi is becoming more common in medical procedures, most of the use has relied on the superelasticity of the wire, rather than its hysteretic qualities. One reason for this is the difficulty in heating NiTi wire in situ, without damaging adjacent tissue. This research explores the use of focused ul

Abstract Shape memory alloys (SMA) are a lightweight and compact option for actuators because of their high energy density capacity and allowing the system weight to be reduced by a fraction of conventional actuators. An SMA processed into wire with a narrow hysteresis and great thermomechanical stability can ease integration into novel actuation designs. These designs can improve the thermomechanical response and reduce the energy usage, weight, and mechanical complexity of the system.

Abstract:

The simulation of a flexible finger, actuated with the shape memory alloys (SMAs) artificial muscles, is presented in the paper. The finger is modeled as a cylindrically rod with three embedded NiTi wires in a n aluminum matrix. Forces between NiTi wires causes bending in any plane perpendicular to the longitudinal axis of the finger. The NiTi wires are heated above the austenitic start temperature by passing an electrical current, and the deflected wire tends to return to the initial configuration. Using characteristics of SMAs such as high damping capacity, super-elasticity, thermo-mechanica

Abstract:

Abstract Compared to conventional engineering materials, NiTi shape memory alloys deform via a wide range of deformation mechanisms owing to the B2⇔B19’ martensitic transformation, including twinning in martensite and plastic deformation by dislocation slip. A detailed understanding of the functional properties of NiTi requires comprehensive knowledge of all deformation processes possibly activated in thermomechanical loads. A stress-temperature diagram (Fig. 1c), constructed from the results of isothermal (Fig. 1a) and isostress (Fig. 1b) tensile tests on superelastic NiTi wire (Fig. 1a,b), p

Abstract:

Optimal design of SMA structures must be based on a deep knowledge of the material properties. As the SMA structures increase in complexity (stents, textiles, microdevices), modeling becomes increasingly involved. Macroscopic models of shape memory alloys are being developed with the ultimate aim to effectively simulate thermomechanical response of a constitutive material element. Computational robustness, stability, adaptability and reasonable computational time with respect to the modeling goal becomes however an issue which seems to play an ever increasing role. For instance, the non-propor

Abstract:

Abstract Stainless steel 316L (SS316L) and Nickel-titanium alloy (NiTi), which are additively manufactured metallic biomaterials, are explore for their biocompatibility and mechanical properties in bio-implant applications. The nickel-titanium alloy (NiTi) has been suggested for exceptional thermal shape memory, super elasticity, and high damping qualities compared to Stainless steel 316L (SS316L). In this present study, the input process variables such as voltage, wire-feed rate, dwell time and argon gas flow rate have been maintained constantly (fixed) based on the trial experiments. The met
