Resumo: Non-destructive tests that use the principle of wave propagation have the potential to predict the mechanical properties of wood while still in the field, if the variables of this process are known. This work aimed to estimate the modulus of elasticity to static bending of Eucalyptus sp. wood, using two non-destructive techniques: ultrasound and stress wave. For this, 60 specimens with nominal dimensions of 2.5 x 2.5 x 57.5 cm (tangential x radial x longitudinal) were used, being in equilibrium humidity. The non-destructive tests were carried out using an ultrasound and a stress wave equipment, while the destructive static bending tests were carried out in a universal testing machine. The experimental results showed that the elastic modulus obtained by the non-destructive techniques were superior to that obtained by the destructive technique. The adjusted mathematical models presented standard error of the estimate (Syx) of 11.39 and 10.78%. There was a positive mean correlation between the static and dynamic module. Stress wave and ultrasound techniques can be used to estimate the modulus of elasticity of Eucalyptus sp.

Este trabalho teve o objetivo de estimar o módulo de elasticidade à flexão estática da madeira de Eucalyptus sp., por meio de duas técnicas não destrutivas: ultrassom e stress wave. Para tal foram usados 60 corpos de provas com dimensões nominais de 2,5 x 2,5 x 57,5 cm (tangencial x radial x longitudinal), estando na umidade de equilíbrio. Os testes não destrutivos foram realizados por meio de um equipamento de ultrassom e um de ondas de tensão, enquanto que os testes destrutivos de flexão estática foram realizados em uma máquina universal de ensaios. Os resultados experimentais mostraram que os módulos de elasticidade obtidos pelas técnicas não destrutivas foram superiores à obtida pela técnica destrutiva. Os modelos matemáticos ajustados apresentaram erro padrão da estimativa (Syx) de 11,39 e 10,78%. Logo, houve correlação média positiva entre o módulo estático e dinâmico. As técnicas de ondas de tensão e ultrassom podem ser empregadas com o intuito de estimar o módulo de elasticidade da madeira de Eucalyptus sp.Universidade Federal de Santa Maria2023-09-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/7001910.5902/1980509870019Ciência Florestal; Vol. 33 No. 3 (2023): Publicação Contínua; e70019Ciência Florestal; v. 33 n. 3 (2023): Publicação Contínua; e700191980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/70019/61693Copyright (c) 2023 Ciência Florestalhttp://creativecommons.org/licenses/by-nc/4.0info:eu-repo/semantics/openAccessCarvalho, Romário AlvesSilva, Gilson Fernandes daPinheiro, Christiano Jorge GomesMastela, Leonor da CunhaSouza, Clara Gaspar Fossi deGamas, Alehando LopesSegundinho, Pedro Gutemberg de Alcântara2023-09-19T21:43:36Zoai:ojs.pkp.sfu.ca:article/70019Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2023-09-19T21:43:36Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
