Longtime behavior of Kirchhoff plate equations with internal damping

Longtime behavior of the Kirchhoff plate equations with locally distributed internal damping is studied. The equation is equipped with either homogeneous Dirichlet boundary conditions of zero order and second order, or Robin boundary conditions of first order and third order. Under some assumptions on the damping, it is shown that sufficiently smooth solutions of the equation decay logarithmically.
