A viscoelastic body which undergoes a thermomechanical process is considered. The evolution of the state variables, i.e., the displacement and temperature "elds, is described by a coupled hyperbolic}parabolic integrodi!erential system. The heat #ux through a portion of the boundary is controlled aut
