Resumo: | 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. doi: 10.4336/2012.pfb.32.69.109 |

Para isto, utilizou-se um emissor de ondas ultrassônicas, o qual teve sua sensibilidade avaliada através da comparação com os valores obtidos no ensaio destrutivo de flexão estática. Os resultados evidenciam que a constante elástica dinâmica pode ser utilizada para inferência não destrutiva da rigidez e resistência da madeira de Eucalyptus grandis, entretanto com ressalvas, pois os ajustes observados foram relativamente baixos, com R²aj. de 0,25 e 0,39, respectivamente. doi: 10.4336/2012.pfb.32.69.109Embrapa Florestas2012-03-21info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/mswordhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/272Pesquisa Florestal Brasileira; v. 32 n. 69 (2012): jan./mar.; 109Pesquisa Florestal Brasileira; Vol. 32 No. 69 (2012): jan./mar.; 1091983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/272/252https://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/272/999Vivian, Magnos AlanSantini, Elio JoséModes, Karina SoaresCarvalho, Douglas EdsonMorais, Weslley Wilker CorrêaSouza, Joel Telles deSusin, Felipeinfo:eu-repo/semantics/openAccess2017-04-28T12:57:12Zoai:pfb.cnpf.embrapa.br/pfb:article/272Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2017-04-28T12:57:12Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
