Abstract
We consider the thermoelastic plate system, u(u) - gamma Delta u(tt) Delta(2)u + alpha Delta theta = 0, theta(t) - kappa delta theta - alp ha delta u(t) = 0 and we make a comparison between the models in which gamma = 0 and gamma > 0. We conclude that in the first case the plate system is of a parabolic type, while when gamma > 0 the corresponding system has a hyperbolic behaviour. (C) 1998 B. G.
