The equilibrium equationsare used in the model. Realistic domain are created by using CT scan data. Different cases of static loads and different boundary conditions are used in the simulation. The finite element method is utilized to determine total displacement and Von Mises Stress. The influences of human weight during horizontal walking are investigated. This model will give the useful for surgeon in femur surgeries. The results show that higher weight provides higher total displacement. And it is found that the Von Mises stress affects the lateral femur.Mahidol UniversityComputer ScienceMathematicsArticleSCOPUS
