We consider a dynamical one-dimensional nonlinear von Kármán model for beams depending on a parameter and study its asymptotic behavior for large, as . Introducing appropriate damping mechanisms we show that the energy of solutions of the corresponding damped models decay exponentially uniformly with respect to the parameter . In order for this to be true the damping mechanism has to have the appropriate scale with respect to . In the limit as we obtain damped Berger–Timoshenko beam models for which the energy tends to zero exponentially as well. This is done both in the case of internal and boundary damping. We address the same problem for plates with internal damping.

AB - We consider a dynamical one-dimensional nonlinear von Kármán model for beams depending on a parameter ${\varepsilon }&gt; 0$ and study its asymptotic behavior for $t$ large, as ${\varepsilon }\rightarrow 0$. Introducing appropriate damping mechanisms we show that the energy of solutions of the corresponding damped models decay exponentially uniformly with respect to the parameter ${\varepsilon }$. In order for this to be true the damping mechanism has to have the appropriate scale with respect to ${\varepsilon }$. In the limit as ${\varepsilon }\rightarrow 0$ we obtain damped Berger–Timoshenko beam models for which the energy tends to zero exponentially as well. This is done both in the case of internal and boundary damping. We address the same problem for plates with internal damping.
