Femur bone is one of the most commonly fractured bones in human body, especially for the elderly. It is one of the longest and largest bones found in human beings. In this paper, stress analysis of femur bone is studied by the help of finite element simulation to provide more insight in designing bio-aided equipment or protective sports equipment. The simulations were performed using the software Lisa. The Von Mises stress and displacement magnitude were studied. The stress analysis show that the Von Mises stress reaches up to 46.82 MPa. The Von Mises stress must be less than the yield stress of the material; otherwise it could lead to fracture of the bone. Keywords: finite element simulation, femur bone, Von Mises stress.
