A Methodology for Optimizing Tenon Geometry Dimensions of Mortise-and-Tenon Joint Wood Products

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