Reorientation mechanisms and pseudoelasticity in iron nanowires

open access: yesJournal of Physics D: Applied Physics, 2011
Using molecular dynamics simulations we present the ⟨1 1 0⟩ → ⟨0 0 1⟩ reorientation and pseudoelasticity induced by axial strain in iron nanowires. The reorientation mechanism shows an intricate dependence on the deformation temperature. Specifically, the original ⟨1 1 0⟩ nanowires and the reorientated ⟨0 0 1⟩ counterparts exhibit pseudoelastic ...

Limits of Pseudoelasticity in Gold Nanocrystals

open access: yesThe Journal of Physical Chemistry C, 2021
Pseudoelasticity in metal nanocrystals allows for shape recovery from strains much larger than their bulk counterparts. This fascinating property could be used to engineer self-healing or reconfigurable materials, but to take full advantage of its ...

Pseudoelasticity of Excised Visceral Pleura

Journal of Biomechanical Engineering, 1987
A pseudostrain-energy function is proposed for describing the behavior of excised sheets of canine visceral pleura. Pseudoelastic material constants are determined from experimental biaxial data by employing a nonlinear least-squares algorithm. The agreement between theory and experiment is shown to be quite good.

Twinning pseudoelasticity in InTl

Acta Metallurgica, 1983
Abstract Twin boundaries generally contribute significantly to the damping of a twinned crystal. In an In-19.1 at.% Tl single crystal the damping gives rise to automodulation if the internal friction studies are performed in the 10 Hz frequency range, with a strain amplitude larger than 0.05 and at temperatures lower than 10°C.

The Interior of the Pseudoelastic Hysteresis

MRS Proceedings, 1991
AbstractAn interesting problem within the research on shape memory is provided by the investigation of the pseudo-elastic hysteresis loop that accompanies the strain-induced austenitic-martensitic phase transition. Miller [1] suggested by thermodynamic arguments that the size of that loop should be related to the coherency energy at interfaces between ...

Shape memory effect and pseudoelasticity behavior in tetragonal zirconia polycrystals: A phase field study

open access: yesInternational Journal of Plasticity, 2014
Martensitic tetragonal-to-monoclinic transformation in zirconia is a double-edged sword , enabling transformation toughening or shape memory effects in favorable cases, but also cracks and phase degradation in undesirable scenarios.
