Thus, the relationship between the test span (L) and the specimen height (h) greater than or equal to 21 (L/h ≥ 21) is respected, ensuring that the effect of shear in the calculation of displacements is negligible (Euler Bernoulli Theory). Considering the expressive number of tree species cataloged in the Brazilian Amazon Forest, any procedure that aims to facilitate the realization of experimental tests is highly desirable because it provides the knowledge of unusual species. These wood species may potentially replace woods that have been traditionally used and historically exploited. Using five hardwood species, this research aimed to verify, while maintaining constant L/h ≥ 21 ratios, the influence of specimens dimensions in the determination of fM and EM. For all species studied, the statistical analysis found equivalence in the values of fM and EM determined as a function of the sample sizes. Therefore, respecting the ratio L/h ≥ 21, the size of the specimens does not influence the determination of strength and stiffness in static bending.engUniversidade Federal de Minas GeraisUFMGBrasilENG - DEPARTAMENTO DE ENGENHARIA MATERIAIS E DA CONSTRUÇÃO CIVILBioResourcesMadeiraEstruturas de madeira (construção civil)Propriedades mecanicasHardwoodsMechanical propertiesTimber structureInfluence of specimen dimensions in the determination of strength and modulus of elasticity in static bending of hardwoodsinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://bioresources.cnr.ncsu.edu/resources/influence-of-specimen-dimensions-in-the-determination-of-strength-and-modulus-of-elasticity-in-static-bending-of-hardwoods/João Paulo Boff AlmeidaEdson Fernando Castanheira RodriguesFernando Júnior Resende MascarenhasAnderson Renato Vobornik WolenskiEduardo ChahudLuiz Antonio Melgaço Nunes BrancoRoberto Vasconcelos PinheiroFrancisco Antonio Rocco LahrAndré Luis Christoforoapplication/pdfinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFMGinstname:Universidade Federal de Minas Gerais (UFMG)instacron:UFMGLICENSELicense.txtLicense.txttext/plain; charset=utf-82042https://repositorio.ufmg.br/bitstream/1843/60749/1/License.txtfa505098d172de0bc8864fc1287ffe22MD51ORIGINALInfluence of specimen dimensions in the determination of strength and modulus of elasticity in static bending of hardwoods.pdfInfluence of specimen dimensions in the determination of strength and modulus of elasticity in static bending of hardwoods.pdfapplication/pdf243953https://repositorio.ufmg.br/bitstream/1843/60749/2/Influence%20of%20specimen%20dimensions%20in%20the%20determination%20of%20strength%20and%20modulus%20of%20elasticity%20in%20static%20bending%20of%20hardwoods.pdf95ba83078a73b99c7064a3fb0b62b4f4MD521843/607492023-11-09 18:42:52.894oai:repositorio.ufmg.br:1843/60749Repositório de PublicaçõesPUBhttps://repositorio.ufmg.br/oaiopendoar:2023-11-09T21:42:52Repositório Institucional da UFMG - Universidade Federal de Minas Gerais (UFMG)false |
