Cosserat curve model for superelasticity of helices [PDF]

Nanotechnology, 2009
Superelasticity behavior of helices has been the focus of recent research in micro-/nano-engineering, while the traditional Kirchhoff rod model restricts itself in the bending and torsion conditions. With the aid of the concept of a Cosserat curve, a novel theoretical basis has been established for statics and dynamics of helices with essential ...

Superelastic collisions of electrons with excited Mn⁺ [PDF]

Journal of the American Society for Mass Spectrometry, 1990
Excited Mn(+) ions formed by electron ionization of Mn2(CO)10 are deexcited in superelastic electron-ion collisions. The ions are held in the trap of a Fourier transform ion cyclotron resonance spectrometer and subjected to bombardment by an electron beam of varying energy. The population of excited Mn(+) ions after exposure to the beam is monitored by

Flexocaloric effect in superelastic materials

APL Materials, 2022
We present a combined theoretical–experimental study of flexocaloric effects in superelastic materials exhibiting structural transitions. We study a Ginzburg–Landau model combined with a vibrational model for a beam near a ferroelastic transition loaded with a three-point bending setup.

Micromechanical Modelling of the Superelastic Behavior [PDF]

Le Journal de Physique IV, 1995
Shape Memory behavior in polycrystalline material is very sensitive to the local stress state. To take this features into account, we have developed a micromechanical approach based on a kinematical description of the physical strain mechanisms and a definition of a local thermodynamical potential.
