Shape Memory Effect in Cu Nanowires

Nano Letters, 2005
A rubber-like pseudoelastic behavior is discovered in single-crystalline face-centered-cubic (FCC) Cu nanowires in atomistic simulations. Nonexistent in bulk Cu, this phenomenon is associated primarily with a reversible crystallographic lattice reorientation driven by the high surface-stress-induced internal stresses due to high surface-to-volume ...

A non-isothermal phase field study of the shape memory effect and pseudoelasticity of polycrystalline shape memory alloys

Computational materials science, 2019
In this paper, a non-isothermal phase field (PF) model is proposed to investigate the shape memory effect (SME) and pseudoelasticity (PE) of polycrystalline shape memory alloys (SMAs) with consideration of the latent heat effect.

The triple-shape memory effect in NiTi shape memory alloys

Smart Materials and Structures, 2012
We report two approaches to realize the triple-shape memory effect (SME), i.e., returning to the original shape from the temporary shape through one intermediate shape in a gradual/step-by-step heating induced recovery, in NiTi shape memory alloys (SMAs).

Triple-shape memory effect in a styrene-based shape memory polymer: Characterization, theory and application

Composites Part B: Engineering, 2019
A segmented styrene-based shape memory polymer (SMP) comprising two types of SMP materials (S1-SMP and S2-SMP) was fabricated by using a two-step curing method to exhibit the triple shape memory effect (triple-SME).

Numerical Simulations on Shape Memory Effect of Shape Memory Polymer

Key Engineering Materials, 2010
Shape memory polymer (SMP) is being used in many engineering fields due to its shape memory effect and the advantages of large recoverable strain, excellent manufacturability, light weight, low cost and bio-degradability. Therefore it is of practical interest to investigate its thermo-mechanical behaviors.

Triple Shape Memory Effect of Star-Shaped Polyurethane

ACS Applied Materials & Interfaces, 2014
In this study, we synthesized one type of star-shaped polyurethane (SPU) with star-shaped poly(ε-caprolactone) (SPCL) containing different arm numbers as soft segment and 4,4'-diphenyl methane diisocyanate (MDI) as well as chain extender 1,4-butylene glycol (BDO) as hard segment.

A three-dimensional phenomenological model for shape memory alloys including two-way shape memory effect and plasticity

Mechanics of materials (Print), 2019
The one-way and two-way shape memory effects (SMEs) as well as the thermal hysteresis represent fundamental properties when dealing with the design of detachable and thermally-stable connection systems based on shape memory alloys (SMAs). Such properties

On the origin of the improvement of shape memory effect by precipitating VC in Fe–Mn–Si-based shape memory alloys

Acta Materialia, 2018
We studied the role of VC precipitation in improving the shape memory effect (SME) of the as-solution treated Fe–Mn–Si-based shape memory alloys by examining the microstructures developed during aging and deformation using transmission electron ...
