ABSTRACT = {Various methods in the literature proposesequations to calculate the stiffness as a function of density of bone tissue such as apparent density and ash density among others[Helgason, Perilli, Schileo, Taddei, Brynjolfsson and Viceconti, 2008]. Other ones present a value of an equivalent elasticity modulus, obtained by statistical adjustments of curves generated through mechanical compression tests over various specimens[Chevalier, Pahr, Allmer, Charlebois and Zysset, 2007; Cuppone, Seedhom, Berry and Ostell, 2004]. Bone tissue is a material withdifferent behaviors according to the scale of observation. It has a complex composite hierarchical structure, which is responsible for assign optimal mechanical properties. Its characteristics, composition and mechanical properties depend on the level at which the material is evaluated[Fritsch and Hellmich, 2007; Hamed, Lee and Jasiuk, 2010]. This paper presents a methodology for computational mechanical simulation of trabecular bones based on the mechanical properties of their elements, hydroxyapatite, type I collagen and non-collagenous proteins with water, and the concentration of these ones obtained by microtomography.},
