Correlation between Dry Density and Volumetric Shrinkage Coefficient of Three Brazilian Tropical Wood Species

Wood is a material of natural origin, whose properties are strongly influenced by their anatomical characteristics. In order to define a better interaction of the properties, studies aim to relate them in empirical equations past researches propose an experimental equation involving the density of the material and the coefficient of volumetric shrinkage, admitting the existence of a linear dependence between the variables in question. This work aims to evaluate the correlation between dry density and volumetric shrinkage coefficient in three Tropical Wood species: Cedrella sp., Cassia ferruginea and Vataireopsis araroba, separately evaluated and the three species together. Results shows that linear correlation between oven dry density and volumetric shrinkage coefficient in the three species together, but a different ratio than found in literature. To generalize the findings obtained here, further studies with larger number of species are required.
