Best fit obtained to estimate the strength values of wood by apparent density – geometric a and linear b models Considering the significant adjustment in Table 4 and 5, it demonstrates the representativeness of the apparent density as an estimator of strength and stiffness properties of Cedrelinga catenaeformis Ducke wood. The use of wood also meets the requirements cedrelinfa the current environmental appeal of products and services provided by man [].

Thus, Cedrelinga catenaeformis Ducke appears as a very interesting option, especially to Brazilian Amazonian Region, the west and southeast part of Brazilian country, where the occurrence of this wood specie is more noticeable [5]. Tornillo has some of the largest pores of any commercial wood catennaeformis the world. Arnaldo Uliana February 6, at 7: Heartwood is light to golden brown.

Projeto de estruturas de madeira. Conclusions The results of this study permit us to conclude: The estimation of strength and stiffness properties by density via mathematical methods regression methods could enable the engineers a better pre-design of the structure. Design and analysis in experiments. Leave A Comment Cedreliinga reply Comment.

Aiming to contribute to the use of new wood species in building construction, mainly in structural purposes, as well as other 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.

Coarse, uniform texture with moderate natural luster. Floresta e Ambiente, 25 1 Variation of wood density and mechanical properties of blackwood Acacia menaloxylon R. These large pores give it a unique open texture, with the pores appearing as thin dark veins on all facegrain surfaces.

Full Characterization of Calycophyllum Multiflorum wood specie.

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.

All stiffness properties met 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. Best fit obtained to estimate the strength values of wood by apparent density – geometric a and linear b models.

Rio de Janeiro, p. However, it is timely to register the high number of required tests, aspect that causes a high cost for wood characterization equipment and xatenaeformis. Considering that density is a fundamental property, its values can endorse determining an appropriate estimate of some wood properties [1, 2, 7, 8, 9]. Mechanical properties results for the Cedrelinga catenaeformis Ducke wood. 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.

Besides the standard health risks associated with any type of wood dust, no further health reactions have been associated with Tornillo. Tornillo also has a common name in Brazil: Turns, glues, and finishes well. In this context, it seems important to search alternatives to reduce costs and, in this paper, it is catenaeforis to correlate all mechanical properties with density.

Prices are moderate for an imported hardwood. A company located in Brazil https: Tropical South America Tree Size: Tables 4 and 5 shows the best fits by property obtained using regression models for apparent density in the estimation of the values of strength cedrelingz stiffness, respectively. Grain is straight to slightly interlocked.

No characteristic odor though green lumber can have an unpleasant scent. 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. A picture of slab doors make with Cedroarana.

Wood, a natural and sustainable resource, has been used by humankind for several purposes especially in construction and some manufacturing sectors. 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. Journal of the Korean Wood Science and Tecnology, v.

Results and Discussion 4.

Intenetional Journal of Materials Engineering6 5: Moreover, the use of ANOVA, which allows to accept or not the representativeness cedrelinnga the tested models, the coefficient of determination values R catenaeformid were obtained as a way to evaluate the capability of the apparent density to explain the estimated dependent variable. The best fit for the estimation of f H0 and f H90 were the geometric and linear illustrated in Figure 1.

Cerne, Lavras MGv. Mechanical and physical properties measured for the Cedrelinga catenaeformis Ducke wood specie. Rated as moderately durable; poor insect resistance.
