Wood cells are composed of cellulose, hemicellulose, and lignin compositions. The particular compositions may be geometrically idealized as a set of hollow cylinders in a mutual contact on their surface areas, whilst the continuous displacements and stress state transmission are assumed being right on the cylinder surface areas. Stress development phenomena influenced by the wood cell elongation in the axial direction is investigated within the work presented in this paper. Overall nine parameters defining the orthotropic elastic material characteristics are applied for the particular constituents. Regarding the numerical modeling, a transversely isotropic constitutive model of was opted as a simplification, an analytical solution of the stress state was driven by the ideas of displacement method. All the material parameters applied in the models were estimated in compliance with relevant references. Transversal contraction phenomena was the most focused on within the presented investigation and all the considerations and conclusions are summarized at the end of this paper.
