Sientific results:

1. Mathematical model of the thermomechanics for the electrickeep non ferromagnetic solids under influence of the external unstationary electromagnetic fields, specifically under:

a) induction heating by harmonious steady and quasi- steady electromagnetic field, also by unsteady one with taking account of transitional regimes of induction heating;
b) magnetic impacts with finite velocity of magnetic field growth up to fixed values on body surface;
c) influence of amplitude-modulated radio-wave pulses on the surface;
d) influence of aperiodical electromagnetic pulses to the adiabatic process of solids deforming by impulse electromagnetic field.

2. Initial equation systems has been obtained for dynamical problems of thermoelasticity and electromagnitoelasticity in the stress. The boundary values problem are formulated for the founding of dynamical thermomechanics behaviour for the electrickeep solids under above-noted unsteady electromagnetic influences.

3. Solution method of the dynamical problems of the thermoelasticity in the stress and electromagnitoelasticity (homohenegous and layered) has been developed for:

a) the solids with flat boundaries - space and plain problems;
b) the cylindrical solids - plain, axialsymmetrix and space problems.

4. Conformity change to natural laws in time and on co-ordinates is investigated for Joule heat release, electromagnetic pondemotive forces, temperature and stress-tensor components under induction heating by quasi-steady and unsteady under influence of magnetic impacts, aperiodical electromagnetic impulses, and amplitude-modulated radio-wave pulses. Thermomechanics behaviour of solids on the resonance frequencies of electromagnetic fields also has been explored.
