In the present research, an investigation of the mechanical behavior of plywood sandwich panels, consisting of plywood surfaces and corrugated or ribbed plywood core, has been performed using finite element analysis. Four-point bending numerical model has been developed according to the test set up described in EN789. Each birch veneer ply and its orientation have been introduced for assembly of the laminate stacking sequence in ANSYS finite element simulation. The required input parameters, like single ply material mechanical properties, were obtained from unidirectional veneer specimen tension tests performed as part of this study. Results from finite element calculations were verified with experimental strain and deflection measurements performed using sandwich panel prototypes. A good agreement has been acquired between numerical and experimental results, with average discrepancy of 10 %.
