DETERMINATION OF POISSON´S RATIO OF THE Guadua angustifolia Kunth USING IMAGE PROCESSING AND ITS RELATIONSHIP WITH THE MICROSTRUCTURE. Rev.Fac.Nal.Agr.Medellín [online]. 2007, vol.60, n.2, pp. 4067-4076. ISSN 0304-2847.
The technique of image processing was applied to determine the values of the Poisson's ratio for the Guadua angustifolia Kunth, in the cepa and the basa of the element, besides to analyze the incidence of its internal structure in this property. The results indicated that the Poisson's ratio depends upon the material structure reaching values between 0,22 and 0,35 making of this biological product a material highly heterogeneous and anisotropic. In addition the microstructure analysis of conductive tissue, parenchyma and fibers, indicated that these components vary through the cross-sectional section of the guadua element.
