Abstract

We study numerically the long-time evolution of waves of a thin elastic plate for different energy input. In particular, we focus on the possible existence of intermittency, intended mainly as highly non-gaussian features. We show that deviations from the Kolmogorov- Zakharov scenario are present in high-order structure functions of the deplacement. This is more pronounced for higher-energy input even though the limit of small deformation so that modes of oscillations interact weakly is globally kept valid.
