Resumo
This paper is concerned with a viscoelastic Kirchhoff plate featuring variable material density. It is modeled by the equation (Formula presented.) defined in a bounded domain of R N , where ϱ = |u t | ρ accounts for a velocity-dependent material density. It is known that its analogue second-order wave equation can be exponentially stabilized with the sole dissipation given by the memory term. However, for the plate equation, exponential stability was only shown with an additional strong damping −Δu t . Our objective is to show the exponential stability of the present system by exploring only the memory term.
