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.

Mechanisms of the multi-shape memory effect and temperature memory effect in shape memory polymers

Soft Matter, 2010
As recently demonstrated, after programming, thermo-responsive shape memorypolymers can exhibit the multi-shape memory effect (SME) upon heating. In addition, it is confirmed that the temperature corresponding to the maximum recovery stress in constrained recovery is roughly the temperature at which pre-deformation is conducted, a phenomenon known as ...

Shape memory effect in FeMnNiAl iron-based shape memory alloy

Scripta Materialia, 2019
Abstract The development of Iron-based shape memory alloys holds significant promises for cost-sensitive applications. FeMnNiAl has been attracting increasing interest due to high levels of superelasticity across a wide range of temperatures (−196–300 °C). However, shape memory effect for this alloy system has not been demonstrated.

Optimization of the shape memory effect in shape memory polymers

Journal of Polymer Science Part A: Polymer Chemistry, 2011
AbstractIn this article, we show that given a thermoresponsive shape memory polymer, it is possible to alter a number of its properties, such as the recovery temperature, shape fixity ratio, maximum recovery stress, and final recovery stress (and even a right combination of some of them, e.g., the maximum recovery stress and final recovery stress ...

Shape Memory Effects

2004
Understanding shape memory requires a thermodynamic approach that takes into account the structure of the solid and the mechanical properties resulting from it. For this reason, the crystallographic and thermodynamic aspects of shape memory effects will be discussed below to the extent to which they are relevant to the development of microactuators ...

Tunable polymer multi-shape memory effect

Nature, 2010
Shape memory polymers are materials that can memorize temporary shapes and revert to their permanent shape upon exposure to an external stimulus such as heat, light, moisture or magnetic field. Such properties have enabled a variety of applications including deployable space structures, biomedical devices, adaptive optical devices, smart dry adhesives ...

Development of zwitterionic copolymers with multi-shape memory effects and moisture-sensitive shape memory effects

Journal of Materials Chemistry B, 2015
This paper describes a new kind of zwitterionic copolymer having a multi-shape memory effect and a moisture-sensitive shape memory effect from DMAPS and acrylic acid (AA). In addition to dual-SME, the copolymer also shows triple-SME and quadruple-shape-memory effect.

TIG Welding and Shape Memory Effect of TiNi Shape Memory Alloy

Journal of Intelligent Material Systems and Structures, 1996
In the present study, with respect to TIG welding for a TiNi shape-memory alloy wire and sheet, the optimum welding schedule was decided based on the breaking load of the weld and its standard deviation. By performing the cyclic loading-unloading and heating-cooling tests in the neighborhood of the weld, the shape memory effect was investigated.
