Cardiovascular stents are life‐saving devices and one of the top ten medical breakthroughs
of the 21st century. Decades of research and clinical trials have taught us about the effects of …

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 …

Fabrics are ubiquitous materials that have conventionally been passive assemblies of
interlacing, inactive fibers. However, the recent emergence of active fibers with actuation …

One of the challenging issues in studying the fatigue behaviors of NiTi shape memory alloy
is the interaction between the material damage and material's martensitic phase …

The structural fatigue life of nanocrystalline NiTi wires with grain size ranging from 53 nm to
125 nm was improved by stress-controlled mechanical training and the percentage of the …

Nitinol implants, especially those used in cardiovascular applications, are typically expected
to remain durable beyond 108 cycles, yet literature on ultra-high cycle fatigue of nitinol …

In this paper, a multiscale investigation of fatigue crack initiation in shape memory alloys
(SMAs) based on Transformation Induced Plasticity (TRIP) is presented. A mechanism for …

There is a growing body of evidence that “in situ” modification of the microstructure of Nitinol
due to pre-strain and mean strain strongly influence the fatigue properties of implanted …

Shape memory alloys (SMAs) are often used in applications involving time-varying loads.
Under such conditions, fatigue leading to possible fracture is a paramount cause of failure …

The present study develops a hybrid total life and damage-tolerant fatigue methodology for
the determination of a small crack growth threshold in Nitinol. Axial tension–tension/Mode I …
