I will examine the system of thermoelasticity endowed with polyconvex energ y. I will show that we can embed the equations of polyconvex thermoviscoel asticity into an augmented\, symmetrizable\, hyperbolic system which posse sses a convex entropy. This allows to prove many important stability resul ts\, such as convergence from the viscous problem to smooth solutions of t he system of adiabatic thermoelasticity in the zero-viscosity limit. In ad dition\, I will present a weak-strong uniqueness result in the class of en tropy weak solutions and in a suitable class of measure-valued solutions\, defined by means of generalized Young measures. Also\, we will discuss a variational scheme for isentropic processes of adiabatic polyconvex thermo elasticity: I establish existence of minimizers which converge to a measur e-valued solution that dissipates the total energy\, while the scheme conv erges when the limiting solution is smooth.\n LOCATION:https://researchseminars.org/talk/VMAS/24/ END:VEVENT END:VCALENDAR
