Abstract
Beech wood is a material whose importance in the wood industry is growing. In the manufacture of many different products, e.g. frame furniture, it is essential to know the compressive strength in connection with buckling of wood. The performed tests allow us to carry out a precise comparative analysis of compression and elastic buckling of beech wood. The similarity of the curves of the compression ratio to deformation for these processes shows that compression strength is directly related to shear strength of elementary wood fibres. Compression strength was calculated and the limit of the limit of stress proportionality scope was estimated. The elasticity modulus was determined using three methods, and unanimous results were obtained. On the basis of those measurements the limits of slenderness ratio for elastic buckling were calculated. Cubic interpolation was used in the theoretical description of plastic buckling. Additionally, the used model provided a reliable estimation of the limit slenderness ratio between plastic buckling and pure compression. Keywords:
