“…The results of investigation of the strength of the two most frequent joints in the upholstered furniture frames (mortise and tenon joints and double dowel joints), constructed with two wood species and the use of two adhesives (PVAc and PU) showed that the mortise and tenon joint in combination with PVAc, provided the best strength for all investigated wood species (Vassiliou et al 2016). In an investigation of effect of wood species and adhesive type on the stiffness of rail to leg mortise and tenon furniture joints, the type of glue was not important for spruce joints, whereas for beech, the stiffness of joints glued with PVAc was significantly higher than with PU adhesive (Záborský et al 2017). In comparison with PVAc, PU glue has appropriate strength, and, as they slightly expand during the hardening phase, can completely fill and cover the gaps between elements of joint (Hrovatin et al 2013).…”

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.

“…The permanent joints are usually composed of mortise-and-tenon (M-T) members with different wood species (Smardzewski 2008;Záborský et al 2017), glue line thickness and distribution (Kasal et al 2013;Ratnasingam and Ioras 2013;Džinčić and Živanić 2014), fits (Wang and Lee 2014;Elek et al 2020), and tenon geometry (Demirci et al 2020), which has been widely used since ancient times (Wu et al 2020). Hence, the M-T joints, especially those connected by rectangular or round blind-tenon, are favored by woodworkers and consumers due to the advantages of externally invisible and outstanding static and dynamic strength performance under a reasonable engagement (Zhang et al 2001;Erdil et al 2005;Likos et al 2013;Chevalier et al 2019).…”

The cantilevered leg joint commonly used in modern wood furniture was studied by numerical and experimental methods. A novel joint was proposed and compared with the typical joint commonly used in the cantilevered leg. Both of them were made of beech wood (Fagus orientalis Lipsky). The experimental results showed that the bending moment capacity of the novel joint was remarkably higher than the typical joints, which confirmed that the novel structure had a better mechanical performance. The numerical analysis was conducted according to GB/T 10357.3 standard, the results showed that the stresses of the typical joint were mainly concentrated on the wooden components, while the stresses of the novel joint were concentrated on the metal connectors. The stress concentration obtained by the finite element method (FEM) was consistent with the failure modes of the experimental tests, which provides a reliable method for evaluating and optimizing the novel furniture structure.

“…Additionally, Erdil et al [16] reported that the effect of tenon width on bending moment resistance was more significant than tenon length. Furthermore, the effects of tenon thickness on the bending elastic stiffness of samples were investigated, and the results suggested that the effect of tenon thickness on the bending elastic stiffness was more significant [17].…”

For a long time, the geometry dimensions of tenons have been designed through empirical methods, which is not beneficial to designers and manufacturers and results in more time spent in construction and a greater amount of waste wood materials. In this study, an optimal methodology of combining finite element analysis (FEA) with response surface method (RSM) was proposed to investigate the effect of tenon geometric dimensions (length, width, and thickness) on withdrawal and bending load capacities of mortise-and-tenon (M-T) joints, with the aim of making the design of wood products more scientific. The following results were concluded: (1) the effect of tenon length on withdrawal load capacity was greater than tenon thickness, followed by tenon width; (2) the effect of tenon thickness on bending load capacity was greater than those of tenon width, followed by tenon length; (3) it was concluded that the tenon length should be designed to be greater than the tenon width and smaller than twice the tenon width, especially, when tenon thickness was relatively thin; (4) quadratic models can be used to predict the withdrawal and bending load capacities of M-T joints relating the length, width, and thickness of the tenon; (5) the proposed method was capable of being used to optimize the tenon sizes and get more knowledge of M-T joints visually. This study will contribute to reducing the costs of time and materials, and it will result in M-T joints being designed more rationally.
