Study of dynamics of the fracture nucleation in a crystal material deformed

Abstract

Computational modeling of the dynamics process of fracture in a deformed crystal material is presented. Molecular dynamic technique using allows to show some important features of the physical nature of the fracture nucleation , linked with size-effects, involving wave processes. Some physical characteristics of the system are determined in classical approximation and sufficiently good accordance with known experimental date is shown . Results of the paper will be useful for evaluating methods of structural materials, used for building the nuclear power reactors, transportation systems, geophysical areas, when controlled by acoustic emission and other commonly used methods.
