Abstract
The moisture content in wood near the surface depends not only on the current relative humidity in the ambient air but also on preceeding variations. This hysteresis phenomenon of sorption implies in worst case that the moisture content for a given relative humidity may deviate 30-35%. Current mathematical models for hysteresis e.g. the independent domain model are complicated and have numerical deficiencies. The paper presents a new hysteresis model with closed-form expressions and current relative humidity and moisture content as the only input parameters. In addition the method is general for different sorption isotherms, i.e. different species and temperatures.
