Abstract
An analysis is made of the nonlinear dynamics of perturbations of the dislocation density and elastic field using a proposed evolution model which takes into account the negative velocity sensitivity of the def orming stresses. As a result of the evolution of domain instability, i t is observed that periodic and isolated solutions (solitons) exist fo r the initial variables. (C) 1998 American Institute of Physics.
