Resumo: http://dx.doi.org/10.5902/1980509817483Different species of wicker (Salix spp.), planted in region of Canoas river valley (Serra Catarinense), have application in handicraft. The research of their physical and mechanical properties takes into account the processing and handling to manufacturing, as the density of the relevant species, the bending of the rods and traction of tapes. In this paper considerations are made about the use of NBR 7190/1997 with a view to carry out physical and mechanical tests in wicker, evaluating adjustments made in the equations indicated by the normative document, in the preparation of specimens and also in the testing machine accessories. Dimensional aspects of the test samples to the bulk density (12% moisture) were reconsidered, obtained by the stereometric and by displacement of mercury methods. Because of dimensional differences of the material used in handicraft, the analysis of each test were made separately, evaluating rods for the bend study and the material transformed in tapes for the tension test, being direct with little transformation in cutlass and nipper. The equations were adapted to minimize the influence of inertia moment on transversal section were adapted, in the bend case. For wicker properties analysis, the adaption of wood standard is suitable.

A pesquisa de suas propriedades físicas e mecânicas leva em consideração o seu processamento e o manuseio para manufatura, sendo relevantes a densidade das espécies, a flexão dos ramos e a tração de fitas. Neste trabalho são realizadas considerações sobre o emprego da NBR 7190/1997 com vistas à realização de ensaios físicos e mecânicos em vime, avaliando as adaptações realizadas nas equações indicadas pelo documento normativo, na preparação dos corpos de prova e também nos acessórios da máquina de ensaio. Foram reconsiderados aspectos dimensionais das amostras para ensaio de obtenção da massa específica aparente (umidade de 12%), obtida pelos métodos estereométrico e por deslocamento de mercúrio. Em virtude das diferenças dimensionais do material utilizado no artesanato, as análises foram feitas em separado, avaliando-se os ramos para ensaios de flexão e o material transformado em fitas para os de tração, sendo conduzidos mediante pequenas alterações no cutelo e nas garras. Foram adaptadas equações para minimizar a influência do momento de inércia da seção transversal, no caso da flexão. A adaptação da norma NBR 7190/1997 é adequada para a determinação das propriedades do vime, em função das características específicas do material para uso em artesanato.Universidade Federal de Santa Maria2015-03-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/1748310.5902/1980509817483Ciência Florestal; Vol. 25 No. 1 (2015); 249-255Ciência Florestal; v. 25 n. 1 (2015); 249-2551980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/17483/10506Vargas, Carlos AlbertoNascimento, Marilzete Basso doNisgoski, SilvanaMuñiz, Graciela Inés Bolzon deinfo:eu-repo/semantics/openAccess2017-04-11T18:40:38Zoai:ojs.pkp.sfu.ca:article/17483Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-04-11T18:40:38Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
