Abstract
In this study, a basic model was introduced to predict the biomechanical behaviors of the wood in relation to the composite structure of the wood cell wall and its formation. Based on the newly-introduced model, the origins of tree growth stress, anisotropic shrinkage of the wood due to moisture desorption, and the species-dependency of the elastic modulus along the grain were simulated. Through those simulations, it is expected that the fine structure and internal property of each cell wall constituent can be clarified.
