Numerical and analytical analysis of the stress- strain relations to extended beech plywood. The study presents a theoretical and numerical analysis of problems connected with the determination of strength parameters in multilayer beech plywood with varied layer configurations. Analytical calculations were performed in accordance with the classical theory of thin plates lamination in view of the theory of elasticity taking into consideration the Kirchhoff-Love hypothesis. The analyses focused on models of composite layers in plane stress. Values of components of transformed stiffness matrices were estimated theoretically together with those of flexibility in the axial and non-axial configurations of individual laminate layers. A verification was made of analytical calculation results with computer simulation results made on numerical models using the finite element method (FEM). Results of investigations are presented in the form of tables, graphs and graphic visualization of FEM calculations. Keywords: FEM calculations, lamina strength.
