“…As shown in Fig. 5, there is a positive linear correlation between dowel center spacing and bending strength for chamfered joints, which is dissimilar to those of other observations and studies on the influence of dowel center spacing on bending strength in two mediumdensity fiberboard structural members and two Japanese white birch dowels L-shaped joints [9,27], in which the structure is that two dowels side by side joined two structural members; however, the joint in this study was joined by the upper and lower dowels.…”

“…The stability of wood structures depends significantly on the solidity and stability of the joints, and the bending strength and tensile strength are two common strength types of mortise-and-tenon joints [3,4]. Many factors affect the bending and tensile strength of mortise-and-tenon joints, such as moisture content, type of joint, type of adhesive, interference fit and clearance fit parameters between dowel and components, dowel spacing, dowel diameter, dowel insertion depth [5][6][7][8][9].…”

The traditional tenon and mortise joint has low processing efficiency and a weak theoretical basis, making the structure easy to deform and damage, reducing the safety, and increasing waste of resources. This study aims to determine the optimum dowel center spacing parameter for chamfered-joint components and the maximum value of the strength of joints loaded into bending strength and tensile strength. In this study, an integrated optimization method combining the single-factor test and one-way ANOVA analysis was proposed to study the influence of the dowel center spacing on the bending strength and the tensile strength of chamfered-joint components made by Cupressus funebris wood. The results revealed that the bending strength of chamfered-joint components decreases linearly with the increase of the dowel center spacing. In addition, the tensile strength of chamferedjoint components increases first and then decreases with the increase of the dowel center spacing, showing parabola change. The relational expression between dowel center spacing, the bending strength, dowel center spacing and the tensile strength were obtained.

“…Meanwhile, Ming and Jianhua [17] have validated that finite element analysis (FEA) may be used to analyse plastic and elastic deformation of materials and point out areas that are vulnerable to damage and failure. In addition, finite element analysis (FEA) has also been used in the modelling and simulation of furniture structure analysis and studies on the evaluation of timber products using FEA has been established.…”

Kapur (Dryobalanops spp.) is one of the Malaysian common species used for structural construction material. It is capable of serving as a beam and column. This study focused on the experimental mortise and tenon connection fastened with wood; glass fibre reinforced polymer (GFRP), and steel dowel. The finite element method (FEM) was used to model the behaviour of mortise and tenon joint for wood dowel subjected to pull-out loads using ABAQUS software. The experimental results were used to validate a three dimensional finite element model of mortise and tenon joint. The full structural scale ofmortise and tenon was fastened with a 21 mm diameter dowel. The investigation was carried out by applying tensile loads to the top of the tenon. This study adopted a linear elastic orthotropic material to represent the Kapur wood behaviour using the FEM. In this study, the results reveal the load carrying capacity of the mortise and tenon in a sequence of highest to the lowest is when the joint dowelled with GFRP, steel and wood. The stiffness value obtained from the FEM for wood dowel is found higher than the experimental value. Thus, the findings from finite element method (FEM) and the experimental results both had slightly dissimilar load–displacement curve shape. However, this study contributes to a better knowledge of mortise and tenon performance when secured with a wood dowel.

Oriented strand board (OSB) veneer technology and its performance have been widely studied in order to expand the range of OSB substrates. In this paper, OSB was a modified composite with boards as substrates, Myanmar old mahogany bark as the veneer material, and a cornstarch adhesive. Under such conditions, the optimal veneer technology was studied, and the index of the surface bonding strength and the veneer penetration rate were utilized in order to determine the performance. Two different processing technologies, cold pressing and hot pressing, were experimentally compared and hot pressing showed better performance. Subsequently, experiments were performed on the surface bonding strength and veneer penetration rate. The results show that the veneer performance of OSB is best when the unit pressure is 1.0 MPa, the hot-pressing temperature is 90 °C, and the hot-pressing time is 240 s. Furthermore, the magnitude of influence of the factors affecting the bonding strength is as follows: unit pressure > hot-pressing temperature > hot-pressing time. The research results have prospective significance for the performance optimization of OSB veneer technology.
