Design and analysis in experiments. According the regression models, only two properties were considered significant with apparent density estimation. Extra sanding or very sharp tools may be necessary to obtain a smooth finish.

Besides, with the analysis of variance ANOVAtesting several regression models, it has hoped to estimate the values of strength and stiffness as a function of apparent density. Coarse, uniform texture with moderate natural luster. Propriedades da Madeira de Pinus caribaea e Eucalyptus grandis.

This turned possible to determine, among the considered significant models 4 models for each of the 12 strength properties and estimated stiffness — resulting in 48 adjustmentsthe ones with the best fit.

Projeto de estruturas de madeira. Regression models for the stiffness values estimation of the Cedrelinga catenaeformis Ducke by the apparent density. European Journal of Wood and Wood Products, v.

Tornillo also has a common name in Brazil: Heartwood is light to golden brown. No characteristic odor though green lumber can have an unpleasant scent.

Prices are moderate for an imported hardwood.

Turns, glues, and finishes well. Introduction Wood is an important and sustainable material employed in several sectors and industries of different segments nowadays and it has been used to quench humankind demands, like store food, construction of shelters and agricultural tools. Thirteen specimens were used for each test, totalizing experimental results. Intenetional Journal of Materials Engineering6 5: Considering the high-level demand and few options of well-known wood species for structural construction and manufacture purposes, predatory and selective harvesting has reduced market receptivity for new species whose characteristics and properties are not yet known.

Results and Discussion Tables 2 and 3 shows the mean values coefficient of variation Cvthe lowest Min and the highest Max of the physical and mechanical properties of the Cedrelinga catenaeformis Ducke wood, respectively. The mechanical properties of Cedrelinga catenaeformis obtained demonstrated compatible performance with regular wood species used in temporary civil construction.

It should be noted that 13 values for each one of its physical 3 and mechanical properties 12 were investigated, resulting in experimental values obtained. In consequence, the prices on market were meanly affected and it got confirmed it is indispensable to define new species to replace the traditional ones used in building construction [1, 3].

Due to predatory harvest of well-known wood species and in consequence, possible shortage of these essences, it is indispensable to characterize new wood species. Rio de Janeiro, p. Considering that density is a fundamental property, its values can endorse determining an appropriate estimate of some wood properties [1, 2, 7, 8, 9].

Besides, it must be remembered that some specific testing machines are available only in research centers. Leave A Comment Cancel reply Comment.

Mechanical and physical properties measured for the Cedrelinga catenaeformis Ducke wood specie. Tropical South America Tree Size: Rated as moderately durable; poor insect resistance. Journal of the Korean Wood Science and Tecnology, v. In this context, it seems important to search alternatives to reduce costs and, in this paper, it is intended to correlate all mechanical properties with density.

Aiming to contribute to the use of new wood species in building construction, mainly in structural purposes, as well as catenaecormis applications, this study intended to determine the physical and mechanical properties of Cedrelinga catenaeformis wood specie and evaluate the possibility of estimating strength and stiffness properties investigated by density. Leave this field empty. To use of wood rationally in a large range of possibilities, the knowledge of its anatomical, chemical, physical and mechanical properties is crucial.

Besides the standard health risks associated with any type of wood dust, no further health reactions have been associated with Tornillo. catenaeformiis

Moreover, the use of ANOVA, which allows to accept or not the representativeness of the tested models, the coefficient of determination values R 2 were obtained as a way to evaluate the capability of the apparent density to explain the estimated dependent variable.

Results and Discussion 4. All stiffness properties catennaeformis the values of the coefficients of variation required by the standard and all strength properties exceed the limit but hardness normal to the grain fH90 which attended the limit, showing a Cv equal to 0. Mechanical properties results for the Ecdrelinga catenaeformis Ducke wood.

Best fit obtained to estimate the strength values of wood by apparent density – geometric a and linear b models. Save my name, email, and website in this browser for the next time I comment. Very large, open pores also give a pronounced veined look to facegrain surfaces.
