Abstract
The features of perturbation propagation in a copper crystal grain under local high-energy loading conditions were studied. The process was studied by method of molecular dynamics using multiparticle model potentials calculated within the framework of the embedded atom approximation. It is shown that a nonlinear solitary pulse is formed in the crystal, which is capable (in contrast to the case of a linear perturbation) of transferring the energy at a high density over relatively large distances. The energy transfer range depends both on the area and on the rate of local loading.
