The slope of the curve in Figure 5 indicates a unit of dimensional change per unit change of moisture, i.e., an index that compares the dimensional stability of wood, namely, the moisture expansion coefficient X.
Sorption of water is known to change material properties by hydro-plasticization [1] and changes the volume by moisture expansion [2].
For isotropic materials the mass and volume fractions of water can be related to the volumetric coefficient of moisture expansion [[alpha].sub.H] by:
