Regularizing properties and propagations of singularities for thermoelastic plates
Jaime E. Muñoz Rivera, Luci Harue Fatori · Mathematical Methods in the Applied Sciences · 1998
We consider the thermoelastic plate system, utt−γΔutt+Δ2u+αΔθ=0, θt−κΔθ−αΔut=0 and we make a comparison between the models in which γ=0 and γ>0. We conclude that in the first case the plate system is of a parabolic type, while when γ>0 the corresponding system has a hyperbolic behaviour. © 1998 B. G. Teubner Stuttgart—John Wiley & Sons, Ltd.
