Abstract | ||
Although doweled joints are vastly used in furniture frame, these are little. Information about its withdrawal strength. The intent of this study is both to obtain initial and primary information concerning the withdrawal strength of dowel pin and, as far as possible, to develop generalized expression to estimate its strength. In this study, the effect of dowel diameter from three levels of 6, 8 and 10 mm and two penetration depth levels of 9 and 12 mm on withdrawal strength has been investigated. The results show that the highest withdrawal strength belongs to dowel with diameter of 8 mm and penetration depth of 12mm. Based on statistical results the experimental model of has been obtained to predict withdrawal strength. | ||
