The system involves constantbheat conductivity and the specific heat satisfying the Einstein-Debye (θ3+θ)-law. Such nonlinear law, relevant at relatively low temperatmes, represents the main novelty of the paper. The existence of global regular solutions is proved without small data assumption. The crucial part of the proof is the strictly positive lower bound on the absolute temperature θ. In case of the Debye θ3-law this still remains an unsolved problem. The existence of local in time solution is proved by the Banach successive approximations method. The global a priori estimates are derived with the help of the theory of anisotropic Sobolev spaces with a mixed norm. Such estimates allow to extend the local solution step by step in time.}, title={Three-Dimensional Thermo-Visco-Elasticity with the Einstein-Debye (θ3 + θ)-law for the Specific Heat.Global Regular Solvability}, type={Text}, URL={http://www.rcin.org.pl/Content/197735/PDF/RB-2017-12.pdf}, keywords={Existence of global regular solutions, Istnienie globalnych regularnych rozwiązań, Kelvin-voigt type materials, Sobolev spaces with a mixed norm, Materiały typu kelvina-voigta, Przestrzenie sobolewa o normie mieszanej, Thermoviscoelastic system, Einstein-debye law for specific heat, System termo-wiskoelastyczny, Prawo einsteina-debye'a dla ciepła właściwego}, }
