Regression models for the strength values estimation of the Cedrelinga catenaeformis Ducke by the apparent density. Considering that density is a fundamental property, its values can endorse determining an appropriate estimate of some wood properties [1, 2, 7, 8, 9].
Projeto de estruturas de madeira. Mechanical and physical properties measured for the Cedrelinga catenaeformis Ducke wood specie. Grain is straight to slightly interlocked.
Tornillo has some of the largest pores of any commercial wood in the world. Variation of wood density and mechanical properties of blackwood Acacia menaloxylon R. Leave A Comment Cancel reply Comment. It demonstrate the relation between these properties and the apparent density but unable to use them as an estimator of catenaefkrmis properties due its poor adjustment. Intenetional Journal of Materials Engineering6 5: 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.
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.
The use of wood also meets the requirements that the current environmental appeal of products and services provided by man . The estimation of strength and stiffness properties by density via mathematical methods regression methods could enable the engineers catenaefrmis better pre-design of the structure.
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.
Tornillo | The Wood Database – Lumber Identification (Hardwood)
Physical properties results for the Cedrelinga catenaeformis Ducke wood. Turns, glues, and finishes well.
European Journal of Wood and Wood Products, v. 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 cwdrelinga determine the physical and mechanical properties of Cedrelinga catenaeformis wood specie and evaluate the possibility of cateneaformis strength and stiffness properties investigated by density.
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.
A picture of slab doors make with Cedroarana. Propriedades da Madeira de Pinus caribaea e Eucalyptus grandis. Leave this field empty. Cerne, Lavras MGv.

Compared with Liquidambar sp. Heartwood is light to golden brown. Conclusions The results of this study permit us to conclude: Coarse, uniform texture with moderate natural luster.
Wood, a natural and sustainable resource, has been used by humankind for several purposes especially in construction and some manufacturing sectors. Journal of the Korean Wood Science and Tecnology, v.

Evaluating the apparent density of Cedrelinga catenaeformis 0. These large pores give it a unique open texture, with the pores appearing as thin dark veins on all facegrain surfaces.
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. However, it is timely to register the high number of required tests, aspect that causes a high cost for wood characterization equipment and services.
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.
Besides the standard health risks associated with any type of wood dust, no further health reactions have been associated with Tornillo. Density, some anatomical properties and natural durability of stem and branch wood of two tropical hardwood species for ground applications.
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. Rio de Janeiro, p. Floresta e Ambiente, 25 1 Mechanical properties results for the Cedrelinga catenaeformis Ducke wood. The best fit for the estimation of f H0 and f H90 were the geometric and linear illustrated in Figure 1. 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].
Besides, it must be remembered that some specific testing machines are available only in research centers.
The mechanical properties of Cedrelinga catenaeformis obtained demonstrated compatible performance with regular wood species used in temporary civil construction. A company located in Brazil https: Best fit obtained to estimate the strength values of wood by apparent density – geometric a and linear b models.
Regression models for the stiffness values estimation of the Cedrelinga catenaeformis Ducke by the apparent density. Cfdrelinga 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. Rated as moderately durable; poor insect resistance.
