We assume that the energy dissipation occurs on a portion of the boundary via a nonlinear (noncoercive) velocity feedback. Under some technical conditions imposed on the nonlinear terms, we prove that the energy of the entire system decays uniformly to zero when the time \(t\to\infty\). In contrast with other works on related topics we do not assume any geometric coefficients on the controlled portion of the boundary.For the entire collection see [Zbl 0771.00032].
