| description | This study presents preliminary results of the basic properties of the
northern red oak wood as well as the relationship between the properties of
the core samples obtained on the live tree and the tested properties. The
core samples 5 mm in diameter were extracted from the tree and used for
determining the fractometer properties: compressive strength parallel to
grain, radial bending strength and braking angle. Using descriptive
statistics and multiple regression, the relationship between fractometric
parameters and basic physical and mechanical properties of wood determined
by destructive methods (wood density, compressive strength in parallel with
fibers and bending properties (bending strength and modulus of elasticity).
The obtained values of the examined properties of northern red oak are
within the limits of the literature data. Statistical analysis has shown
that radial bending strength cannot be used as a reliable fractometric
parameter in assessing wood quality. On the other hand, the obtained results
suggest that the relationship between the other two parameters (compressive
strength parallel to grain and fracture angle) and the properties of the
northern red oak wood can be successfully described using the multiple
regression models (coefficient of determination ranged from 0.945 to 0.990). |
