Journal ArticleDOI
Tight-binding potentials for transition metals and alloys.
Fabrizio Cleri,Vittorio Rosato +1 more
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.
Ravi Prasher,Xuejiao Hu,Yann Chalopin,Natalio Mingo,K. Lofgreen,Sebastian Volz,Fabrizio Cleri,Pawel Keblinski +7 more
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.
