Abstract
This work presents data analysis of the acoustic emission (AE) signals released by raw bamboo specimens subjected to monotonic tensile tests. Bamboo wood samples were extracted from the full culm of Bambusa Vulgaris species. A spectral analysis of the AE signals was conducted. It was found that the material suffers a significant plasticization before breakage of the culm's inner wall. From this point and until the final breakage of the outer wall, an important increase of the center of gravity (CoG) of the signal spectrum was observed. AE signals with CoG above 200 kHz were associated with fiber breakage. © 2019 Taylor & Francis Group, LLC.
