Surface free energy and its effect on the elastic behavior of nano-sized particles, wires and films

R Dingreville, J Qu, M Cherkaoui - Journal of the Mechanics and Physics of …, 2005 - Elsevier
Atoms at a free surface experience a different local environment than do atoms in the bulk of
a material. As a result, the energy associated with these atoms will, in general, be different …

[图书][B] Materials interfaces: atomic-level structure and properties

D Wolf, S Yip - 1992 - cambridge.org
The study of interfaces has boomed since the early 1970s primarily owing to their central
role in microelectronics, processing, and phase transformations, to mention just three areas …

Molecular‐dynamics study of the synthesis and characterization of a fully dense, three‐dimensional nanocrystalline material

SR Phillpot, D Wolf, H Gleiter - Journal of applied physics, 1995 - pubs.aip.org
A molecular‐dynamics simulation method is described that permits space‐filling, fully dense
three‐dimensional nanocrystalline materials to be grown by crystallization from the melt. The …

Atomic-scale mechanism of crack-tip plasticity: dislocation nucleation and crack-tip shielding

F Cleri, S Yip, D Wolf, SR Phillpot - Physical Review Letters, 1997 - APS
By isolating the process of dislocation emission from a crack tip under an applied tensile
stress, we extract from a molecular dynamics simulation the atomic-level displacement and …

A semi-analytical method to compute surface elastic properties

R Dingreville, J Qu - Acta Materialia, 2007 - Elsevier
In this paper, a semi-analytic method is developed to compute the surface elastic properties
of crystalline materials. Using this method, surface elastic properties, such as the intrinsic …

Interfacial excess energy, excess stress and excess strain in elastic solids: Planar interfaces

R Dingreville, J Qu - Journal of the Mechanics and Physics of Solids, 2008 - Elsevier
In this paper, interfacial excess energy and interfacial excess stress for coherent interfaces
in an elastic solid are reformulated within the framework of continuum mechanics. It is shown …

Structural transformation of partially confined copper nanowires inside defected carbon nanotubes

Y Guo, W Guo - Nanotechnology, 2006 - iopscience.iop.org
The encapsulated copper atoms inside a defected single-walled carbon nanotube escape
from the tube through the defect hole as the temperature increases. This causes the partially …

Grain boundaries as heterogeneous systems: atomic and continuum elastic properties

I Alber, JL Bassani, M Khantha… - … Transactions of the …, 1992 - royalsocietypublishing.org
The relation between atomic structure and elastic properties of grain boundaries is
investigated theoretically from both atomistic and continuum points of view. A …

Evaluation of thermal conductivity and its structural dependence of a single nanodiamond using molecular dynamics simulation

H Matsubara, G Kikugawa, T Bessho… - Diamond and Related …, 2020 - Elsevier
In the present study, we investigated thermal conductivity and its structural dependence of a
spherical nanodiamond with 2.5 nm in diameter using molecular dynamics simulation. We …

Atomistic simulations of materials fracture and the link between atomic and continuum length scales

F Cleri, SR Phillpot, D Wolf, S Yip - Journal of the American …, 1998 - Wiley Online Library
The macroscopic fracture response of real materials originates from the competition and
interplay of several atomic‐scale mechanisms of decohesion and shear, such as inter …
