Superelastic softening in perovskites
Physical Review B, 2011Contrary to high frequency (MHz-GHz) elastic data, at low frequencies (0.1-50 Hz) huge elastic softening (superelasticity) is usually found in the low symmetry improper ferroelastic phases (i.e., tetragonal or rhombohedral) of perovskite structured materials including SrTiO3, KMn1-xCaxF3, and LaAlO3.

A Superelastic Helicotome for Capsulorhexis
2019We design and characterize a novel, single-use device to perform capsulorhexis, a critical step during cataract surgery, during which a 5-mm-diameter incision is made in the anterior lens capsule. This device, the Helicotome, is a hand-held tool based on a superelastic shape-memory-alloy blade to perform the circular incision in the lens capsule.

Leveling of the Second Molar with a Superelastic Spring
Journal of Orofacial Orthopedics / Fortschritte der Kieferorthopädie, 2006Second permanent molars often erupt during fixed appliance treatment. When they are to be incorporated into the fixed appliance, it is often not possible to bond the buccal tube in the correct position.We describe herein a method for aligning second permanent molars by means of a superelastic segmental archwire. This involves the application of a rigid

Superelasticity of CoNiGa:Fe single crystals
Applied Physics Letters, 2005We have fabricated CoNiFeGa single crystals with excellent superelasticity. The superelastic strains of 4% and 6.7% in compression have been obtained along the [001] and [110] directions, respectively. These single crystals show strong anisotropy in strains, superelastic parameters, and even transformation path related to the different crystalline ...

Behaviour in torsion of superelastic NiTi
Materials Science and Technology, 2002AbstractTorque–strain curves have been established at 20 and 37°C and for up to 100 strain cycles for NiTi tube with an A f temperature of—8.5°C. The performance mirrors the behaviour in tension and compression. In the first few strain cycles, the curves exhibit the familiar flag shape, but this gradually changes into a sigmoidal curve on repeated ...

Micropolar elastic percolation: The superelastic problem
Physical Review B, 1988This paper deals with the critical elastic behavior of a two-dimensional micropolar (or "granular") network with randomly rigid or elastic bonds. It presents a new derivation of Feng's inequalities $1l{s}^{\ensuremath{'}}ls$ in the context of micropolar elasticity (where $s$ is the conductivity exponent, ${s}^{\ensuremath{'}}$ the elastic-moduli ...

Superelasticity in Shape-Memory Materials
2003The recently developed crystal-mechanics-based constitutive model of Thamburaja and Anand [8] for superelasticity of shape-memory materials is reviewed and shown to quantitatively predict the superelastic response of an initially-textured Ti-Ni alloy in a variety of reasonably complex deformation modes.
