Abstract
The influence of anisotropic dynamic loading on the character of plastic de formation and fracture processes in a crystallite near the free surface was studied by methods of molecular dynamics. It was established that there ar e threshold deformation levels determining the opening of a seeding crack ( notch) and the subsequent crack stop. The simulation results show that load ing in the [100] direction leads to the crack stop due to the formation of a disordered material region at the crack tip. (C) 2001 MAIK "Nauka/Interpe riodica".
