Using the fundamental principles of thermodynamics of irreversible processes and
continuum mechanics and electrodynamics, a complete set of equations of the
thermomechanics of an electroconducting polarized medium has been obtained by
taking into account the local displacements of mass and electric charge. To determine
the thermodynamic state, two additional state parameters, namely the induced mass
and the gradient of the energy measure of mass displacement, have been introduced.
Two other parameters, the energy measure of mass displacement and the mass
displacement vector, have been coupled to the aforementioned parameters. Such an
extension of the state parameter space allows one to describe the near-surface
inhomogeneity of the stress-strained state and the electric polarization as well as
the surface charges and the electromagnetic signals induced by the surface
formation.
