Light cellular wood panels have been gaining increasing interest among furniture manufacturers, but only a few articles can be found dealing with modeling of mechanical properties of cellular wood panels with a paper honeycomb core inside. The present paper intends to fill this gap, and thus, the elastic properties of cellular wood panels with paper honeycomb of hexagonal and auxetic cells were evaluated. Analytical models have been employed by comparison of experimental data with those obtained by numerical calculations. The cores of the examined cellular wood panels exhibited strong orthotropic properties. Results of numerical calculations of sandwich beam deflections corroborated their satisfactory conformity. The results of laboratory measurements proved the correctness of the determined elastic constants.
