“…5 shows the results of wood species, joint technique, and adhesive type three-way interaction with confidence intervals. The load capacity results under tension loading obtained from this study have been compared with the results in study that were conducted by Imirzi et al (2015). Generally, it could be said that the load capacities of dowel and mortise & tenon joints constructed of beech and oak agree with the results obtained from this study.…”

“…The joint properties are most affected by tenon length [4]. The highest stiffness/strength values were estimated in mortise and tenon joints, whereas dowel joints showed the lowest stiffness/strength and deformability [5]. The same study states that the elasticity modulus of the experimental joints (substitute modulus) expressed their stiffness better than the stiffness coefficient.…”

In this paper, the stress and strain analysis of the frontal parallel joints with two different 3D printed connectors is performed. The connectors were made of PLA material and were bonded to wooden parts (spruce) with a one component polyurethane adhesive. The test was carried out to determine mechanical properties of the joints at the point of failure and proportional limit. Analytical calculations were used to determine: the effective modulus of elasticity of the joints, the normal stress of joint parts and the deflections at two directions. Numerical stress and strain analyses were performed with finite method software. The results show that the ratio between the effective modulus of elasticity of joint and the modulus of elasticity of spruce wood is 0,71 for connector without inner wall and 0,61 for connector with inner wall. The ratio between the appropriate values of the stress and deflection at the point of failure for connector with and without inner wall is approximately 0,80 and also between the appropriate values of the stress and deflection at the point of proportional limit is 0,90. The results also indicate that the analytical and numerical calculations gave reasonable estimates of mechanical behaviour of the joints.

“…For most of the manufacturing and processing operations, many aspects including wood inhomogeneity, changes in environmental conditions and machining parameters are of immense significance. The strength, rigidity and stability of timber are essential factors to be considered for the safe and economical design of the structural elements (Eckelman and Suddarth 1969;Imirzi et al 2015;Jivkov and Marinova 2006). For furniture and other timber constructions, the quality and durability of the various glued structural joints used are significantly influenced by the structural fit of the comprising elements in addition to several other factors (Prekrat and Smardzewski 2010).…”

Evaluation of the effect of optimal fit criteria on the compressive strength of open mortise and tenon corner joints

The study examines the degree of deviation from the nominal size of the produced open full-width mortise and tenon joint elements for their optimal pairing based on the measured thickness and gap width data. The characteristics of the measuring devices used were analysed by the repeatability and reproducibility test. The compressive strength of the single-glued joints (where only the surfaces of the tenon were glued) and double-glued joints (where the surfaces of both the mortise and tenon elements were glued) for various joint fit categories was also determined. It was found that despite the huge number of produced test specimens and their measurements, the joint fits could be maintained with the milling machine and tools. The thickness of the joint could be characterized by measuring the data at the centre of the tenon, whereas the gap width of the mortise could be characterized by measuring the data on the side of the tool leaving the wood. The double-glued joints showed higher breaking force and displacement values as compared to the single-glued joints. The joints were found to be the strongest at a tight fit of 0.1 mm.
