“…Traditional mortise-and-tenon (M&T) joints are widely used in wooden furniture frames (Erdil et al 2005;Wu et al 2020). Previous investigations conducted found several critical factors influencing the service life of M&T joints, e.g., moisture, wood species, adhesive type, heat treatment, tenon size, and tenon geometry (Likos et al 2012;Hajdarevic and Martinovic 2014;Zhou et al 2018;Yan et al 2020;Liu et al 2019;Yang and Liu 2020;Zhou et al 2020;Fu et al 2021a;Yin and Liu 2021;Wu et al 2021).…”

This study aimed to design and evaluate the detachable corner joints used in wooden furniture frames, including a commonly used detachable joint (control) form using mortise and tenon with plug reinforcement and three novel proposed joints, i.e., novel joint I ~ III, which adopted in-line double-hole nuts, metal sheet connector, and embedded nuts and screws respectively, via numerical and experimental methods. The numerical analysis results indicated that the optimal proposed joint (novel joint І) had good mechanical performance when subjected to bending load with proper stress distributions and relatively low maximum stress compared with the other two proposed joints. The experimental results showed that the bending load resistance of the control and the optimal proposed joints were 1920 N (0.14) and 4390 N (0.05), respectively. The bending moment capacity and bending stiffness of the optimal joints were remarkably higher than the bending moment capacity and bending stiffness of the control joint. In addition, the combination of the numerical and experimental methods could effectively simplify the steps of furniture connection design and development and save costs in terms of time and materials.

“…Round tenon is widely used in structures of traditional wood furniture and modern panel furniture due to its advantages of wood savings and its simple structure [4][5][6][7] . However, basic properties of wood, which is a natural polymeric biomaterial, inevitably deteriorate with age due to natural and human intervention; as a result, the mechanical properties of the mortise and tenon joints deteriorate, ultimately affecting the safety of the overall structure [8][9][10][11][12] . Structural strength of furniture products is the basis for realizing product functions; therefore, it is crucial to investigate the mechanical properties of mortise and tenon joints for the safety of solid wood furniture [13][14][15][16][17] .…”

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.

“…As a natural composite material, wood has been widely used in engineering fields including wood constructions and wood products [1][2][3][4]. Compared with other engineering structure materials, such as steel rods and cement concrete, wood has the advantages of being environmental friendly [5,6] and having easy processing [7], good decoration [8][9][10][11][12] and an early warning system before failure [13,14].…”

The fracture behaviors of four wood species commonly used in wood products were characterized when subjected to compact tension (CT) load in radial-longitudinal (RL) system crack propagation. Meanwhile, the failure modes of evaluated CT samples were compared and analyzed using the fractal dimension method. The results showed that wood species had a significant effect on fracture characteristic values, including maximum fracture load, critical stress intensity factor and fracture energy. These characteristic values changed in the same way, i.e., beech wood CT samples obtained the maximum characteristic values, followed by ash, okoume, and poplar in descending order. The fracture behaviors of all wood species evaluated can be described by combining linear and exponential fitting equations at the crack initial stage and evolution stage, respectively. Linear positive proportional relationships were observed between fracture characteristic values and fractal dimensions calculated using cracks in front and left views of CT samples. However, the relationships between fracture characteristic values and fractal dimensions calculated using fracture surfaces were negative. The fractal dimensions of cracks in front view of CT samples could be a better indicator used to predict critical stress intensity factor and fracture energy, which had greater correlation coefficients beyond 0.95.
