Abstract
- This design of high value-added products and the calculus of structures in wood requires reliable elastic characteristics related to a theoretical model that explains in a rational way the elastic behavior of wood. This research presents the methodology and the results of the experimental determination of the elastic characteristics of two Canadian woods: Acer rubrum and Abies balsamea. The characteristics examined were modulus of elasticity, modulus of rigidity and Poisson's ratio. Compression tests within the elastic regime were performed in the orthotropic directions of wood: radial tangential and longitudinal. The moisture content of A. rubrum was 9% and 10% for A. balsamea. The densities were 651 kg/m³ and 393 kg/m³ respectively. With the empirically obtained characteristics, the properties and orthotropic relations of the elastic constants matrix of the general elastic model were analyzed. The experimental values of the elastic characteristics of A. rubrum and of A. balsamea woods are comparable with values corresponding to these woods determined in other studies. Likewise, it was proved that the orthotropic postulates of the general elastic model are -within some confidence level- valid. [ABSTRACT FROM AUTHOR]
