Journal ArticleDOI

Tight-binding potentials for transition metals and alloys.

TL;DR: The parameters of many-body potentials for fcc and hcp transition metals, based on the second-moment approximation of a tight-binding Hamiltonian, have been systematically evaluated and good quantitative agreement with the experimental data up to temperatures close to the melting point is found.
Journal ArticleDOI

Turning carbon nanotubes from exceptional heat conductors into insulators.

TL;DR: It is shown that the kappa of a packed bed of three-dimensional random networks of single and multiwall CNTs is smaller than that of thermally insulating amorphous polymers.
Journal ArticleDOI

Atomic-Scale Mechanism of Crack-Tip Plasticity: Dislocation Nucleation and Crack-Tip Shielding

TL;DR: In this article, the atomic-level displacement and stress fields on the activated slip plane before and after a crack tip dislocation are extracted from a molecular dynamics simulation, and the role of surface steps in dislocation nucleation and crack-tip blunting is demonstrated.
Journal ArticleDOI

Atomic scale origin of crack resistance in brittle fracture.

TL;DR: It is shown that the widely accepted identification of intrinsic crack resistance with the free surface energy underestimates the energy-release rate, and the strain dependence of the Young modulus and surface energy, as well as allowance for lattice trapping, improve the estimate of the crack resistance.
Journal ArticleDOI

Thermal conductivity from approach-to-equilibrium molecular dynamics

TL;DR: In this article, molecular dynamics simulations were used to study the thermal transport properties of a range of poor to good thermal conductors by a method in which two portions are delimited and heated at two different temperatures before the approach-to-equilibrium in the whole structure is monitored.
