Structural fatigue of NiTi shape memory alloys is a key issue that should be solved in order
to promote their engineering applications and utilize their unique shape memory effect and …

Nitinol (NiTi), a shape memory alloy (SMA) of nickel and titanium, exhibits two unique
properties: the shape memory effect and superelasticity. It is a material of choice for …

In this work, cyclic tension-unloading tests with different peak strains (10%-18%) in the
temperature range from 313 K to 393 K are performed to investigate the effects of …

Motivated by an assumption that the instability of the cyclic tensile superelastic behavior of
NiTi polycrystal is linked to its fatigue performance (number of cycles till failure), the …

A non-isothermal and crystal plasticity based phase field model was established by
incorporating various inelastic deformation mechanisms, ie, martensite transformation …

In this paper, the effects of ambient temperature on the tensile response and superelastic
fatigue behavior of the shape memory alloy (SMA) cable are investigated. The tested SMA …

Abstract A three-dimensional (3D) thermo-mechanical coupled and physical mechanism-
based constitutive model is phenomenologically constructed to describe the rate-dependent …

In this work, the rate-dependent and loading path-dependent cyclic deformation behaviors of
super-elastic NiTi shape memory alloy (SMA) are investigated under multiaxial cyclic …

Experimental results show that the martensite reorientation and reorientation-induced
plasticity play critical roles on the non-proportional multiaxial transformation ratchetting of …

Based on the experimental observations on the anisotropic cyclic deformation of super-
elastic NiTi shape memory alloy single crystals done by Gall and Maier (2002), a crystal …
