Nonlinear model of source of a elastic field
  A general description of the long-range elastic interaction is proposed. The far-field type of the interaction is determined by the way of symmetry breaking of the distribution of the elastic field produced by the topological defect as isolated inclusions. Every topological defect can be present as the source of the elastic field and can be described in the terms of this field. At the short distance the source can be described as nonlinear object which present charge of linear theory of elastic field at the far distance. In this article the nonlinear models of source of a elastic field was proposed.
