Abstract

To model the phenomenon of moisture sorption hysteresis using the independent domain theory, the moisture distribution among the domains must be established. This paper describes a procedure for obtaining such moisture distribution diagram from which may be calculated the moisture content of wood subjected to a series of relative humidity (RH) changes. The procedure is a refinement of the method described by the author in an earlier paper and is more consistent with the concept of independent domains. An alternative approach using numerical methods is also described.
