Determinación de las propiedades físicas-mecánicas de seis variedades de maderas de la región sur oriental del Ecuador -

Abstract

Abstract: In Ecuador there is little scientific information on wood, causing its use to be empirical and inefficient in the construction industry. In this sense, the main objective was to determine the physical-mechanical properties of Almendro, Guararo, Lacre, Porotillo, Romerillo and Yumbingue, from the south-east of Ecuador. And simulate the mechanical tests through the Finite Element Method (FEM) in the ANSYS software. This work was developed in four stages: collection of experimental data from other studies; physical-mechanical characterization using analytical equations; simulation of mechanical tests; and classification of the strengths of each wood, based on standard values, such as modulus of elasticity and modulus of rupture. For the classification, the results obtained between the average of both methods (FEM and experimental) were taken as the final value. The normal density was higher than 0.6 g/cm3 for all species, which determines them as hard woods. The maximum coefficient of variation between the results of both methods was 13.63%. The classification of the species showed that the Porotillo has the highest resistances and, on the contrary, the Romerillo the lowest.
