ABSTRACT

The aim of this study was an analysis of rigidity-strength numerical models based on the finite elements method of housed tenon joints subjected to torsion. The experiments aimed at selecting models which would allow effective solution of various verification tasks associated with the strength and optimisation of constructions in which connections are subjected to significant torsional loads. The research concerned beam and brick model. The results of dislocation provided by brick model in conditions of pure torsion were verified using the results of identical laboratory investigations. Then the dislocations obtained using both models in a complex state of loads were compared. The research proved that the beam model of the housed tenon connection can be employed to simulate torsional deformations of this connection in strength verification and optimization of furniture skeletons. Whereas the observed similarity between the laboratory experiments and the results of numerical calculations arrived at using the brick model allows to believe that the this model can be used successfully for the stress analysis and dimension optimization of connections in skeleton furniture. The distribution of stresses in the constructional node was determined using brick model.

Key words: furniture, joint, model, stiffness, torsion.
