On the spatial and temporal behavior in linear thermoelasticity of materials with voids

The present article studies the spatial and temporal behavior of the soluti ons to the initial boundary value problems associated with the linear theor y of thermoelastic materials with voids. The spatial behavior is described by spatial estimates of Saint-Venant type (for bounded bodies) and Phragmen -Lindelof type (for unbounded bodies) with time-dependent and time-independ ent rates. Some appropriate time-weighted integral measures are used. The t emporal behavior is studied using the Cesaro means of various parts of the total energy. The relations describing the asymptotic behavior of the Cesar o means are established.
