    Abstract

    The influence of anisotropic dynamic loading on the character of plastic deformation and fracture processes in a crystallite near the free surface was studied by methods of molecular dynamics. It was established that there are threshold deformation levels determining the opening of a seeding crack (notch) and the subsequent crack stop. The simulation results show that loading in the [100] direction leads to the crack stop due to the formation of a disordered material region at the crack tip.
