Improvement Strength of Wooden School Chair Manufactured from Curved Laminated Veneer Lumber
This study deals with enhancement of a wooden school chair manufactured from curved sugi (Cryptomeria japonica D. Don) laminated veneer lumber by utilizing the veneer residues of furniture industries. To verify the mechanical performance of the chair, a computer simulation by using a two-dimensional finite element analysis incorporated with Hoffman failure criterion was conducted under the subjected load provided in Japanese Industrial Standard JIS S1021. Although the strength of the chair has been assured from the analytical results, several approaches of modification for the further improvement in mechanical performance of the chair were put forth in this study. Consequently, the effectiveness of each modification plan on the chairs strength improvement was evaluated quantitatively based on the maximum value of Hoffman failure index obtained from the numerical analysis.
