- Abstract
This study aimed to evaluate the use of different ultrasound waves propagation methods to estimate the mechanical properties of ten Amazonian woods. Therefore, angelim-pedra, amescla, cambará, canelão, cedrinho, cumaru, garapeira, itaúba, jatobá and sucupira-preta woods were subjected to ultrasound tests using direct, indirect and semi direct methods of waves propagation in which ultrasound velocity and dynamic modulus of elasticity were determined. The accuracy of each ultrasound waves propagation method was evaluated from destructive tests of parallel compression, with determination of modulus of elasticity and rupture. The dynamic modulus of elasticity obtained by the ultrasound tests was efficient in the prediction of the modulus of elasticity and rupture in parallel compression. The direct method of ultrasound waves propagation allowed to obtain better results to estimate the mechanical properties, in comparison to the semi direct and indirect methods.
