Outline of Final Research Achievements

It has been often difficult to characterize the mechanical properties of wood-based materials, including plywood, medium-density fiberboard (MDF), and paper, accurately because of the significant effects of the measurement method and specimen configuration. In this study, these effects were examined in detail, and several methods for characterizing the elasticity and strength properties of the wood-based materials accurately could be successfully proposed.
