Natural climate stress caused by a hygric change on coated pine samples: Theoretical formulation and experimental validation

Wood is largely used in construction purposes; however, its proneness to changes in the relative humidity can negatively affect its structural integrity. This research paper aims to calculate the amount of hygric stress induced by variations of relative humidity in Scots pine wood. To this end, on the basis of the already conducted experimental tests, a mathematical approach is introduced. This method allows to obtain the values of hygric stress...
