摘要：

We consider the dynamical von Karman equations for viscoelastic plates under the presence of a long-range memory. We find uniform rates of decay tin time) of the energy, provided that suitable assumptions on the relaxation functions are given. Namely, if the relaxation decays exponentially, then the first-order energy also decays exponentially. When the relaxation g satisfies [GRAPHICS] then the energy decays as 1/(1+t)(p). A new Liapunov functional is built for this problem.
