Computational modelling is an effective tool for development of innovative solutions from cross-ply laminates such as plywood. In order to assure accuracy of such method predetermined material properties should be evaluated. Moreover numerical simulations should validated with the physical experiments under various loading conditions. The aim of current research was to determine elastic properties for individual veneer specimens in order to evaluate the input data for further plywood products analyses using FEM commercial code ANSYS. Therefore more than 250 unidirectional veneer specimens with different thicknesses have been tested. These acquired values has been verified using FEM analysis and afterwards used in validation of bone shaped plywood tension test specimens. Some conclusion has been drawn to narrow down the confidence bounds for mechanical properties to be used in design of plywood panels.
