Abstract

This study aimed to evaluate the use of dynamic elastic constant obtained in non-destructive testing, as a parameter to estimate the mechanical properties of stiffness and resistance of Eucalyptus grandis. For this we used an emitter of ultrasonic waves, which had its sensitivity evaluated by comparison with the values obtained in the destructive test of static bending. The results show that the dynamic elastic constant can be used as non-destructive inference of the stiffness and resistance of Eucalyptus grandis, though with reservations, because the adjustments observed were relatively low, with R²adj. 0.25 and 0.39, respectively.
