Modeling of formation of crystallographic shear zone taking into account orientation dependence for copper

The mathematical model of formation of crystallographic shear zone in FCC metals is presented. The mathematical model of formation of crystallographic shear zone in FCC metals is presented. The model allows investigate of energy, scale and temporal characteristics of the elementary crystallographic slip and the shear zone as a whole as well as of the evolution of dislocation loop. The analysis of changes in the shape of a dislocation loop, the kinetic energy per unit length of the dislocation, and the rate of expansion of a dislocation loop for different orientations at room temperature in copper was done.
