  We simulate structure in the vicinity of different size nanovoids using a new
variant of the Molecular Statics, wherein atomic structure in the vicinity of
nanovoids and the parameters that define the displacements of atoms placed in
elastic continuum around main computation cell are determined in a
self-consistent manner. Then we model structure of the surface of different
crystallographic planes. Next, the kinetic equations for shifting rate of void
surface elements located normal to the void surface are obtained. These
equations take into account the dependence of the vacancy flux on strain and
the surface energies of the crystallographic planes. In the next section, we
apply the obtained expressions and simulation results to calculate the shifting
rates of void surface elements for different crystallographic directions. Rates
of displacements in different crystallographic directions for bcc and fcc
metals differ significantly, and for the <100> direction they are greatly lower
than for other directions.
