- Abstract
The industry that uses wood as an input requires, for calculation and design purposes, engineering parameters derived from experimental tests. The objective of the research was to determine the dynamic modulus of elasticity, the quality factor and the material index of 25 wood species. The density and moisture content of the wood were calculated and transverse vibration tests were performed. The values range of wood density was broad. The species Spathodea campalunata resulted to have lower density; and the wood of Dalbergia granadillo was reported with the maximum density. The minimum value of the modulus of dynamic elasticity corresponded to S. campalunata, and the maximum to Tabebuia chrysantha. It was verified that the density of the wood is a good predictor of its dynamic modulus of elasticity. The quality factor correlates well with density. In contrast, the material index does not correlate. The quality factor and the material index normalize the value of the modulus of elasticity, in this case, the dynamic one. These parameters find application to classify a species of wood for a specific use, and to use them as a selection criterion.
