On the temporal behaviour in the bending theory of porous thermoelastic plates

In this paper we consider the bending theory of Mindlin type thermoelastic plates with voids. We study the temporal behaviour of the solution of the boundary-initial value problem of this theory. Assuming that the internal energy density is positive definite, relations describing the asymptotic behaviour of the Cesaro means of various parts of total energy are established. An extension of the results to a large class of thermoelastic materials with voids is given.
