Abstract
Our aim in this article is to study a nonautonomous semilinear wave equation with nonlinear damping and dynamical boundary condition First we prove the existence and uniqueness of global bounded solutions having relatively compact range in the natural energy space Then by deriving an appropriate Lyapunov energy we show that if the exponent in the ŁojasiewiczSimon inequality is large enough depending on the damping then weak solutions converge to equilibrium
