Using atomistic calculations, we study the features of uniaxial deformation of nanotubes made of rolled-up thin [0 1 0] plates of Fe cubic crystals. We find that within a certain range of chiral angles these nanotubes have both negative Poisson’s ratio and axial strain-induced torsion (reverse Poynting’s effect) during tension and compression. The maximum torsion and the minimum value of Poisson’s ratio are observed at chiral angles of and , respectively. We show that Young’s modulus of the…

Similar to carbon, several transition-metal chalcogenides are able to form tubular structures. Here, we present results from systematic theoretical investigations of structural and mechanical

Helical BN and ZnO nanotubes with intrinsic twisting: An objective molecular dynamics study

a, J. Chem. Phys. 130, 071101 (2009)]. At large diameters, by comparing the microscopic strain stored in the tube wall with the continuum predictions, we observe the invalidity of the continuum shell

Metal [100] Nanowires with Negative Poisson’s Ratio

It is shown that metal nanowires with asymmetric cross-sections such as rectangle or ellipse can exhibit negative Poisson's ratio behavior and that the surface effect inducing the asymmetric stresses inside the Nanowires is a main origin of the superior property.

Axial-strain-induced torsion in single-walled carbon nanotubes.

Using classical molecular dynamics and empirical potentials, it is shown that the axial deformation of single-walled carbon nanotubes is coupled to their torsion, suggesting that the response is now dictated by a combination of nonlinear elasticity and CCIEA.

In the paper presented, we continue the research in the elastic properties of seven-constant tetragonal crystals and nano/microtubes. Our previous study concerned tension of this type of structures,

Torsional behavior of chiral single-walled carbon nanotubes is loading direction dependent

The torsion of carbon nanotubes is studied by molecular dynamics simulations. The torsional behavior of a chiral single-walled carbon nanotube (SWCNT) is dependent on the loading directions due to

Torsion-induced mechanical couplings of single-walled carbon nanotubes

Torsion-induced mechanical couplings of single-walled carbon nanotubes (SWCNTs) are studied by using molecular dynamics simulations. We show that these mechanical couplings are strongly dependent on

Negative Poisson's ratios in metal nanoplates.

Numerical and theoretical evidence is provided that negative Poisson's ratios are found in several nanoscale metal plates under finite strains and this behaviour originates from a unique surface effect that induces a finite compressive stress inside the nanoplates, and from a phase transformation that causes thePoisson's ratio to depend strongly on the amount of stretch.
