OSORIO SARAZ, JAIRO ALEXANDER; ESPINOSA BEDOYA, ALBEIRO  and  GARCIA GALEANO, EDUARD A.. EVALUATION OF MECHANICAL PROPERTIES OF THE INTERNAL STRUCTURE OF THE GUADUA WITH MATEMATICAL MODELLING. Dyna rev.fac.nac.minas [online]. 2009, vol.76, n.160, pp.169-178. ISSN 0012-7353.

The internal structure of Guadua angustifolia-kunth bamboo (GAK) was characterized in its middle zone, finding the internal composition of this composite material, such as the percentage of the matrix (parenchyma) and the fibers (fiber cells and conductive tissue). Mechanical properties of the material were found, such as resistance to tension and the Poisson ratio of the material, and the resistance of the fiber and of the matrix. A mathematical model proposed by Chandrupatla & Belegundu (1999), was validated for composites materials, and some equations were found that permit the prediction of the material´s resistance, and also create computational models useful for floor laminates in Bamboo-Guadua. The experimental results did not differ significantly from the results obtained with the mathematical models

Keywords : Mechanical properties of Guadua; anisotropic materials; mathematical modelling.
