Summary
A mathematical model of the mechanical properties of wood which changes its moisture content is presented. This model was applied to the description of wood swelling pressure across the grain. In addition, changes in swelling pressure of wood subjected to cyclic changes of its moisture content (moistening-drying-moistening), as well as permanent deformation of this wood after each cycle was described with the aid of this model. Good qualitative and quantitative agreement was found between results of the theoretical calculations and experimental data obtained by other investigators.
