SPATIAL BEHAVIOR IN LINEAR THEORY OF THERMOVISCOELASTICITY WITH VOIDS

In the present article we study the spatial behavior of the solutions to the initial boundary value problem associated with the linear theory of thermoviscoelastic materials with voids. We prove a set of properties for an appropriate time-weighted surface power function, which allows us to obtain an idea of the domain of influence in linear thermoviscoelasticity with voids. Some spatial estimates of the Saint-Venant type, for bounded bodies, and Phragmen-Lindelof type, for unbounded bodies, are obtained. Such estimates are characterized by time-dependent as well as time-independent decay and growth rates.
