review text: Stresses caused in linear thermoelastic solids by external quasi-stationary electromagnetic field are studied. It is assumed, that interaction of electromagnetic, thermal and mechanical processes occurs through heat generation, ponderomotive forces and thermoelastic energy dissipation. Joulean and related to polarization in alternating field heat generation are taken into account. Ponderomotive forces arising due to charges (Coulomb forces), dipoles (Kelvin forces) and currents (Ampere forces) are taken into account. Determination of parameters of stress state is reduced to solution of corresponding electrodynamics problems and subsequent finding temperature and stress tensor components from the system of dynamical thermoelasticity under known expressions for heat sources and volume forces.
