Abstract

The possibility of structural defect generation in materials with the ideal crystal lattice under dynamic loading conditions in a broad temperature range has been studied by means of molecular dynamics using the embedded atom method with many-body interatomic interaction potentials. It is shown that thermal fluctuations can lead to a jumplike nucleation of defects in the ideal crystal under high-rate deformation conditions. Features of the defect nucleation via this mechanism are analyzed for various temperatures and loading regimes.
