Full-field measurement techniques are now mature. As such, they have profoundly impacted
the experimental mechanics community in recent years. The way that shape memory alloys …

Fine wires and cables play a critical role in the design of medical devices and subsequent
treatment of a large array of medical diagnoses. Devices such as guide wires, catheters …

In situ digital image correlation (DIC) and in situ X-ray diffraction (XRD) are applied to
investigate the effect of temperature on martensitic transformation and plastic deformation in …

The coupling effects of low asymmetry of HCP structure and transient non-uniform
stress/strain states during multi-pass deformation processing cause a great variation in …

In this study, two-dimensional functionally graded NiTi thin plates were created by laser
surface scanning anneal. Owing to the natural degradation of heat penetrating into the …

Complex metallic structures are often manufactured through multi-step forming or casting
processes that induce severe mechanical property variations within the final part. Instead of …

In the present study, a new 3D thermodynamic coupled model is proposed for SMAs. The
behavior of SMA structures is described through several strain mechanisms, each …

Nearly equiatomic NiTi can be strained in tension to several percent and fully recover upon
unloading (pseudoelastic behavior). This property is derived from solid-state transformations …

The bulge test is mostly used to analyze equibiaxial tensile stress state at the pole of inflated
isotropic membranes. Three-dimensional digital image correlation (3D-DIC) technique …

A three-dimensional constitutive model is developed that describes the behavior of shape
memory alloy actuators undergoing a large number of cycles leading to the development of …
