Sažetak

This paper presents numerical analysis of stress and strain conditions of a three-dimensional furniture skeleton construction and its joints. The fi nite volume method is used in the calculation. Orthotropy of
the wood material is accounted for by approximating it with an isotropic material whose elastic modulus and Poisson’s ratio are calculated by employing the least-square method. The displacement of the edge point for the loaded joint was also determined experimentally. The agreement of results of the calculation and experimental data can be considered satisfactory. The numerical results presented in this paper also provided an opportunity for identification of the region with the largest load and strain in the complex chair skeleton construction, which is one of the most complex pieces of furniture.
