Investigation the bending moment resistance of joints fabricated with dowel in the case-type furniture

The goal of this study was to investigate bending moment resistance of doweled joint with plywood members. Joint members were out of 11-ply hardwood plywood (Hornbeam، Beech and Alder) that were 19 mm in thickness. Dowels were fabricated out of Beech and Hornbeam species. Their diameters (6، 8 and 10 mm) and depths of penetration (9، 13 and 17 mm) in joint members were chosen variables in this experiment. Results have shown that bending moment resistance، increases with increase of dowel’s diameter and its penetration depth. Joints made with dowels of Beech had higher resistance than dowels of Beech ones. Highest bending moment resistance (44. 29 N. m) were observed in joint made with dowels of Beech which were 10 mm in diameter and their depth of penetration was 17 mm. Lowest bending moment resistance (12. 08 N. m) was observed in joints having Hornbeam dowels with 6 mm diameter and 9 mm penetrations
