Correlacion Entre La Densidad Y La Flexión Estática Para Eucalyptus globulus Labill. Procedente De La Sabana Cundiboyacense

Abstract

For establishing the correlation between physical properties (basic and anhydrous Density) and mechanical properties (static bending) of Eucallyptus globulus Labill from the Cundiboyacense savanna of Colombia. We proceeded to obtain maximum resistance, the proportional limit and modulus of elasticity, of corrected data from a moisture content of 12%. Statistical analysis was based on the arithmetic mean and standard deviation were statistically validated by the coefficient of variation. Subsequently, to check the normality and homogeneity of variances, we applied the test of Shapiro-Wilk and Levene respectively. To determine the degree of correlation between the physical and mechanical properties was used coefficient of Pearson and Rho of Spearman. The strongest correlation was found between the anhydrous density and ultimate strength of the test tube (R2 = 0.62). To determine the correlation between the standard specimens (ASTM) and the real scale (120 cm long), with the above tests was tested the normality and homoscedasticity. An analysis of variance was then performed and established that the maximum resistance and the proportional limit were not significantly different, while the modulus of elasticity presented differences for the types of test tubes used. Were applied correlations of Pearson and Spearman Rho to see the relation between these.
