A higher-order nonlocal elasticity and strain gradient theory and its applications in wave propagation
C.W. Lim,G. Zhang,J. N. Reddy +2 more
TL;DR: In this paper, a higher-order non-local strain gradient elasticity model is proposed, which is based on the nonlocal effects of the strain field and first gradient strain field.

Wave propagation in carbon nanotubes via nonlocal continuum mechanics
TL;DR: In this paper, the small-scale effect of wave propagation dispersion relation on carbon nanotubes (CNTs) wave numbers and diameters was investigated with two nonlocal continuum mechanics models: elastic Euler-Bernoulli and Timoshenko beam models.

Nonlocal shell model for elastic wave propagation in single- and double-walled carbon nanotubes
TL;DR: In this paper, the effect of carbon nanotube microstructure on wave dispersion was investigated in a wide frequency range up to terahertz region, and the non-local elastic cylindrical shell theory provided a better prediction of the dispersion relationships than the classical shell theory when the wavenumber is large enough for the carbon nano-tubes to have a significant influence.

Prediction of Young's modulus of graphene sheets and carbon nanotubes using nanoscale continuum mechanics approach
Mahmood M. Shokrieh,Roham Rafiee +1 more
TL;DR: In this article, the elastic moduli of graphene sheets and carbon nanotubes were predicted using a linkage between lattice molecular structure and equivalent discrete frame structure. But the results for a graphene sheet show an isotropic behavior, in contrast to limited molecular dynamic simulations.

Exceptionally high Young's modulus observed for individual carbon nanotubes
TL;DR: In this article, the amplitude of the intrinsic thermal vibrations of isolated carbon nanotubes was measured in the transmission electron microscopy (TEM) and it was shown that they have exceptionally high Young's moduli, in the terapascal (TPa) range.
