Numerical evaluation of efforts on the femoral head in a 3D model

Abstract

The human body skeletal system provides support and form. Bones make up this system, giving it rigidity and shape. They are like structures capable of being compressed, susceptible to fields of tension and transformation. We can analyze a stress/strain field by means of the analytical, experimental and numerical methods, being as two last techniques the more often used. The finite element method (FEM) is suggested as a numerical method. The objective of this work is to present the finite element method as a biomechanical process evaluation tool, applied to the skeletal system, particularly to a 3D-femur model. The study of the contours and loads of biomechanical structures, such as the femur, is important for understanding the causes of fractures or even complications of ligaments or the hip joint. It helps in the scope of training teams of clinical professionals. The results show that the finite element modeling produces plausible results that meet the real behavior of the biomechanical structure. The technical aspects of the work make possible the understanding of the applied biomass systems over the human femoral head, and other body bone segments are subject to study obeying the requirements of the presented methodology. Therefore, consistent with the objectives of the work that seeks a tool of finite elements as a methodology to support the training of clinical pictures.
