Wood has been recognized as a prospective industrial material from a viewpoint of a sustainable resource. It is important to know the stress distribution in wood under processes such as the compressing and drying of wood to control the process with suitable conditions. In this paper, wood was modeled as a laminated plate with repeated grading material properties and the stress caused by moisture transfer was treated. Only Fick's law was considered for moisture transfer. We gave grading property to density and other material properties were assumed to be dependent on density. Lorentz's function was used to give the grading of density in annual ring of wood. The influences of annual ring's thickness on the state of stresses were examined by numerical calculations.
