Mechanical Properties of Clonal Eucalyptus Wood

The mechanical properties of wood are important factors to demonstrate its suitability in construction and crafts applications. The aim of this study is to evaluate the mechanical parameters for two clones of eucalyptus wood (E. grandis; E. camaldulensis). At 12 % moisture content, axial compression, axial tension, four-points bending and elasticity dynamic modulus resulting from the propagation of ultrasound in the wood longitudinal direction are investigated. The obtained results show that E. camaldulensis wood exhibits high rupture stress, a higher static modulus of elasticity in both bending and axial tension along with a higher dynamic modulus of elasticity. Additionally, E. camaldulensis has a lower elasticity modulus value in axial compression. There are statistically significant differences (P<0.05) between the mean measured parameters of these two clones of eucalyptus. The results of this study can be used to valorize clonal Eucalyptus wood in timber structures and wood industry.
