Abstract
Tomography constitutes one of the most important non-destructive methods of non-destructive analysis, evaluating the velocity of mechanical waves through the wood and producing images of the radial profile of teak wood by means of impulse. In this paper, the impulse tomography was applied in the wood of 20 Tectona grandis trees and the images were analyzed. The results showed: i) the generation of mechanical waves in wood with mean speed of 1,087 m/s; ii) the variation coefficient of 19.81%, with low variability, demonstrating the effectiveness of the method; and iii) the internal defects in wood detected in tomography images through color difference.
