Nonlinear Boundary Feedback Stabilization for a Semilinear Kirchhoff Plate with Dissipation Acting Only via Moments-Limiting Behavior*

A semilinear Kirchhoff plate with a nonlinear dissipation acting via moments only is considered. It is shown that the plate is uniformly stabilizable with uniform energy decay rates with respect to the parameter g )0 representing rotational forces assumed small.. Moreover, it is shown that the solutions of the Kirchhoff plate converge to solutions of the semilinear Euler]Bernoulli plate, when gª0, which is also uniformly stable in finite energy norm.
