FEM analysis was conducted with the joint as the contact area, and the stress concentration factor of the male wood and female wood was calculated. Based on the results, we proposed a formula to calculate the stress concentration coefficient of male wood and female wood. From the calculation formula, it was possible to obtain the optimum sickle jaw width S when the length of the head portion length L was determined. In addition, a sickle joint was made by using homogeneous material acrylic, a tensile test was conducted, and the validity of the proposed stress concentration calculation formula was examined. As a result, the trends of the experimental result and the analysis result roughly agreed. Therefore, it can be said that the proposed formula is valid.
