Conventional metal alloys can only recover their original shape if subjected to very small elastic deformations. Superelastic alloys (also named pseudoelastic alloys) can recover their shape after deformations as great as ...

The dynamic response to different seismic inputs of an isolated structure disposed on a sliding layer and connected to the ground with a superelastic NiTi device was analyzed. The device allows wires of NiTi to be mechanically ...

The development of a 1-D thermomechanical model for simulating the response of uniaxial superelastic NiTi elements is described. The formulation of the model includes consideration of the dependence of the critical stresses ...

Objective: This paper analyzed whether nickel-titanium closed coil springs (NTCCS) have a different superelastic (SE) behavior according to activation and whether their force plateau corresponds to that informed by the ...

Accumulation of superelastic cycles in NiTi uniaxial element generates changes on the stress–strain response. Basically, there is an uneven drop of martensitic transformation stress plateaus and an increase of residual ...

The hysteretic damping capacity and high recoverable strains characterizing the superelastic response of shape memory alloys (SMA) make these materials attractive for protection systems of structures subjected to dynamic ...

The effects of fretting on Ni-rich ultra-fine grained NiTi superelastic wires have been characterized. Fretting tests have been performed using wire on wire in 90° cross-cylinder configuration until 105 cycles in air at ...

Shape memory alloys (SMAs) showing the superelastic effect, dissipate energy through hysteretic cycles up to large strain amplitudes, without remnant strains after unloading. This effect is associated with a reversible ...
