“…After 150-200 g/m 2 glue was evenly applied on both sides of the outer surface of the tenon and the inner surface of the tenon hole, two L-shaped and T-shaped members were obtained, which were aged in the laboratory for 7 days before being xed on a universal mechanical testing machine in accordance with the clamping method shown in Fig. 6 for pull-out strength testing (Elek et al 2020).…”

To prevent the problem of test chance in solid wood furniture joint strength testing and reduce the destructive test and test costs, the finite element method (FEM) and ABAQUS software were used to establish a cohesion model, which can predict the pull-out strength of L-shaped and T-shaped members using round tenon joints in the presence of adhesives. In addition, the effect of the diameter of the round tenon on the pull-out strength of the joints was investigated. The simulation results revealed that with the increase in the diameter, the pull-out strength of the double round tenon joint increased, indicating that the diameter of the round tenon is a key factor that affects the pull-out strength of joints. Furthermore, errors between the finite element analysis (FEA) results and the average test results of two members with different diameters were less than 15%, and the cloud diagrams of the structural stresses were consistent with the test results. Therefore, the established FEM is confirmed to be accurate and suitable for predicting the pull-out strength of designed round tenon joints in solid wood furniture. This paper provides new ideas and methods for the non-destructive testing of the structural-mechanical properties of solid wood furniture.

“…The effect of fitting for pairing of open full-width mortise and tenon joint elements on the compressive strength of the joint has been investigated. The mortise and tenon joints were found to be the strongest at a tight fit of 0.1 mm (Elek et al 2020).…”

This paper investigated the effect of the tenon length on the strength and stiffness of the standard mortise and tenon joints, as well of the double mortise and tenon joints, that were bonded by poly(vinyl acetate) (PVAc) and polyurethane (PU) glues. The strength was analyzed by measuring applied load and by calculating ultimate bending moment and bending moment at the proportional limit. Stiffness was evaluated by measuring displacement and by calculating the ratio of applied force and displacement along the force line. The results were compared with the data obtained by the simplified static expressions and numerical calculation of the orthotropic linear-elastic model. The results indicated that increasing tenon length increased the maximal moment and proportional moment of the both investigated joints types. The analytically calculated moments were increased more than the experimental values for both joint types, and they had generally lower values than the proportional moments for the standard tenon joints, as opposed to the double tenon joints. The Von Mises stress distribution showed characteristic zones of the maximum and increased stress values. These likewise were monitored in analytical calculations. The procedures could be successfully used to achieve approximate data of properties of loaded joints.
