Finite Element Analysis of the Structural Performance of a Specific Wooden-stool Type and Style

The structural performance and safety of wooden furniture, particularly stools, are some of the essential considerations in design. This study utilizes Finite Element Analysis (FEA) to assess the mechanical behavior of a beech wooden stool under typical load conditions. The stool’s design, which includes four cubic legs connected by mortise-and-tenon joints and dowel, was modeled and analyzed for stress and displacement under applied forces. The analysis incorporated beech wood material properties and simulated loads including distributed force. Results indicate that stress concentrations occur at the rail close to the joint. The dowel and mortise-tenon joints presented close behavior. Both joint types exhibited similar stress and displacement values, with mortise-and-tenon joints experiencing slightly higher stresses. The study highlights areas of potential failure and suggests design modifications to enhance the stool's structural integrity and safety even if the results are not critical for failure.
