摘要：

A mathematical model is proposed to describe the dislocation dynamics during the formation of a crystallographic shear band in metals with fcc structure taking into account elastic interaction of dislocations. The scale, energy, and time characteristics of the formation of a shear band at room temperature have been investigated for copper, aluminum, and lead.
