Выдержка

Processes in a loaded solid have been studied by the method of molecular dynamics. It is established that dynamic vortex structures can form both in the stage of active loading and in the stress relaxation stage. In the latter case, atomic displacements can result in the formation of a periodic system of correlated vortex threads. The lifetime of such dynamic defects may reach tens of nanoseconds, while their characteristic dimensions are on the nanometer scale. It is demonstrated that the system of vortex threads can change the sign of the angular velocity so that atomic displacements taking place within different time intervals virtually compensate each other. The formation of analogous dynamic vortexlike structures in the active stage of loading does not exhibit a periodic character.
