Моделирование влияния масштабного фактора на теоретическую прочность наночастицы с алмазоподобной структурой
Д.А. Закарян, В.В. Картузов
Abstract
The theoretical strength of diamond-like nanoparticles under uniaxial
stretching and compression is calculated by the method of pseudopotential.
The surface energy of a nanoparticle is defined through the energy of
interaction of atomic planes. The functional dependence of the strength on
the size, depression, and form of a nanoparticle (nanoplate, nanobar) is
obtained. The minimum distance from the external surface of a nanobar, where
the theoretical strength coincides with its value for massive samples, as well
as the minimum area of the nanobar base when the theoretical strength does
not depend on the base form, is evaluated.
