Abstract
In electrically conductive composites placed in an electric field, heat is released and nonuniform temperature fields are formed. This circumstance, in turn, induces strains and stresses in such composites. The article solves a sequence of unrelated boundary value problems: electrical conductivity in a field of direct electric current, thermal conductivity, thermoelasticity. It is shown that when an electric current flows in copper-graphite and copper-filled polymer composites, displacements, deformations, and stresses occur even in the case when the components of the composite do not have a piezoelectric effect.
