Variational principle in thermo-electro-magneto-dynamics of micropolar media
- Journal of Technical Physics, 39(2), p.283-295, 1998 .
The variational principle for micropolar continua interacting with thermal, electromagnetic and mechanical fields is formulated. The potential character of the electromagnetic fields (E, B)and the conservation of electric charge, mass and microinertia are postulated. The remaining equations and the boundary conditions are obtained from the variational principle. The expression for the entropy production is obtained too. We conclude that the proposed variational principle describes both the thermodinamically reversible ...
