Zusammenfassung
Ultrasonic wave propagation is a nondestructive method for the determination of mechanical properties. As an orthotropic material, wood presents different properties according to the direction to the grain. Often, only the longitudinal Young’s modulus (EL) is determined, but many projects, using current software tools, require knowledge of the radial and tangential Young’s moduli (ER and ET), the longitudinal-radial, longitudinaltangential and radial-tangential shear moduli (GLR, GLT and GRT respectively) and the Poisson’s ratios for all planes (ν). The mechanical properties of 13 specimens of Castanea sativa from three different Spanish regions were determined. Ultrasonic results for three of the specimens were compared with results obtained by the traditional compression method for the determination of the mechanical properties of wood. The determination of all the elastic constants by compression testing on three of the specimens did not reveal significant differences between both methods for any of the constants.
