摘要

The recent, extensive round robin “Empirical validation of HAM models based on a dedicated HB-CB experiment” underscored the critical role of accurately implementing hygric material properties for reliable prediction of hygrothermal behavior within the hygroscopic range. To better understand how different implementation strategies affect simulation accuracy, this research explores various methods for modeling moisture transfer properties, addressing variability stemming from experimental constraints and data processing uncertainties. Through analyzing simulated hygrothermal responses, this study evaluates the effects of these approaches on predictive accuracy within the hygroscopic range and also emphasizes the importance of accounting for their impact in the over-hygroscopic range.
