Abstract
Numerical analysis computational programs are applied to the research of biological tissues, which have complex forms. Continuous technological advance has facilitated the development of biomodels to evaluate biological tissues of different human body systems using computerized axial tomography to produce complex three-dimensional models that represent the morphological and physiological characteristics of the real tissues. Biomodels are applied to numerical analysis using the Finite Element Method and provide a perspective of the mechanical behavior in the system. In this study, a numerical evaluation was performed by developing a biomodel of the humerus, radius, and ulna (the elbow joint, composed of cortical bone, trabecular bone, and cartilage). Also introduced to the biomodel were the ligaments of the capsule joint, collateral ligaments of the ulna, and collateral ligaments of the radius. The biomodel was imported into a computer program to perform a numerical analysis considering the mechanical properties of cortical and trabecular bone (including elasticity modulus, shear modulus, Poisson relation, and density). The embedding conditions were defined to restrict displacements and rotations in the proximal zone of the humerus, applying a compression load to the other end of the biomodel at the distal area of the radius and ulna. The results are the direct consequence of how boundary conditions and external agents are applied to the structure to be analyzed, and the data obtained show how the behavior of the force applied through the component produces stresses and strains as a whole, as well as for each of the components. These stresses and strains can indicate zones with structural problems and the detection areas causing pain (assisting in a better diagnosis).
