Subsurface mechanoelectromagnetic phenomena in thermoelastic polarized bodies in the case of local displacements of mass

We deduce a complete system of relations of electromagnetothermomechanics of conducting polarized media with regard for the local displacements of masses. It is shown that the set of conjugated parameters specifying the equilibrium thermodynamic state, parallel with temperature and entropy, the strain and stress tensors, electric-field intensity, and polarization, includes two couples of new parameters, namely, the induced mass and the energy measure mu'(pi) of the influence of the displacement of masses on the internal energy and the vector of displacement of masses and the space gradient of the energy measure mu'(pi) appearing if we take into account the local displacements of masses The indicated extension of the space of parameters of state enables us to describe the subsurface inhomogeneity of the stress-stain state and electric polarization, as well as the formation of the surface charge and electromagnetic signal in the process formation of a new surface. The relations obtained with regard for the indicated parameters can be used for the investigation of the electromagnetic emission accompanying the process of formation of new surfaces in the body or the electromagnetic response to the action of external forces.
