Three-dimensional simulation of the femur bone using finite element method

Abstract

In this paper, a mathematical model is developed to simulate three-dimensional femur bone, taking into account the stress distribution and total displacement during horizontal walking. The principles of continuum mechanics, the field equations governing the displacement and stress fields in the femur bone including the stress equilibrium equations are used in the model. Realistic domain is created using CT scan data. Three different cases of static loads and three boundary conditions are used in the simulation. The finite element method is utilized to determine the total displacement and the Von Misses stress. The influences of human weight during horizontal walking are investigated. This model provides useful information for surgeons involved with femur surgeries.
