Rational design of multi-dowel corner joints in case construction

Although dowel joints are Widely used in the construction of case furniture, little information is available about the additive effects of dowels on the ultimate bending strength of multi-dowel joints or optimum dowel spacing. Bending strength tests were carried out on 6.75-, 9-, 11-, and 14-inch-wi...

Description
Summary:Although dowel joints are Widely used in the construction of case furniture, little information is available about the additive effects of dowels on the ultimate bending strength of multi-dowel joints or optimum dowel spacing. Bending strength tests were carried out on 6.75-, 9-, 11-, and 14-inch-wide specimens that were constructed with 2 to 5 dowels in order to evaluate these effects. Specimens were tested both in compression and tension. Test results indicate that maximum strength per dowel is obtained when dowels are spaced at least 3 inches apart. Results also indicate inherent differences in strength between joints loaded in tension and compression. The strength of joints loaded in compression is presumably related to the internal bond strength of the board, whereas the strength of joints loaded in tension is presumably related to the tensile strength of the board
