Applications of Shape Memory Alloys for Neurology and Neuromuscular Rehabilitation
Journal of Functional Biomaterials, 2015 Shape memory alloys (SMAs) are a very promising class of metallic materials that display interesting nonlinear properties, such as pseudoelasticity (PE), shape memory effect (SME) and damping capacity, due to high mechanical hysteresis and internal ...

Pseudoelasticity at Large Strains in Au Nanocrystals [PDF]
Physical Review Letters, 2018 Pseudoelasticity in metals is typically associated with phase transformations (e.g., shape memory alloys) but has recently been observed in sub-10 nm Ag nanocrystals that rapidly recovered their original shape after deformation to large strains. The discovery of pseudoelasticity in nanoscale metals dramatically changes the current understanding of the ...

Large Deformation Constitutive Theory for a Two-Phase Shape Memory Alloy
Engineering Transactions, 2015 In this work we examine significant theoretical issues related to the constitutive modelling of a two-phase shape memory alloy which undergoes large deformations. For this purpose, we propose a new generalized plasticity based model.

Thermodynamics of Ideal Pseudoelasticity [PDF]
Le Journal de Physique IV, 1995 Experimental results are shown for CuZnAl single crystals which summarize the thermal equation of state of these alloys in the pseudoelastic temperature range, i.e. their (P,d,T)- behaviour. For a partial explanation the first and second law of thermodynamics are applied under the assumption that the essential relevant constitutive ingredients are i ...

A concise review of the applications of NiTi shape-memory alloys in composite materials
South African Journal of Science, 2014 Composite materials have increasingly been used in construction and in the aerospace and automotive industries because they are lightweight, strong and corrosion resistant, and because their anisotropic properties can be controlled; maintenance costs are

On the elastic energy invariance of crystal twins
Archives of Mechanics, 2010 An analysis by Zanzotto (1992, 1996) showed that, if crystal twinning is considered as a material symmetry operation, the symmetry groups of many crystals that form twins correspond to the unimodular group, which is the symmetry group of elastic fluids ...
