The problem has the form of viscoelasticity system with capillarity coupled with heat conducstion equation with mechanical dissipation. The corresponding elastic energy is a nonconvex multiple-weel function of strain, with the shape changing qualitatively with temperature. Under assumption on the growth of this energy with respect to temperature, the existence and uniqueness of a global-in-time solutions for large data has been proven. The existence proof is based on parabolic decomposition of the elastiity system and application of the Leray-Schauder fixed point theorem. The main part of the proof consists in deriving Holder a priori estimates by succesive improvement of energy estimates.}, type={Text}, title={Unique Global Solvability in Two-Dimensional Nonlinear Termoelasticity}, URL={http://www.rcin.org.pl/Content/139447/PDF/RB-2002-12.pdf}, keywords={Global existence, Globalna egzystencja, Parabolic regularization, Paraboliczna regularyzacja, Non- linear thermoelasticity}, }
