Vibration analysis of femur bone using Elmer

Femur bone is one of the most commonly fractured bones of human body,especially for the elderly people. It is one of the longest and largest bones found in human beings. In this paper,vibration analysis of femur bone is studied by the help of finite element simulation to provide more insight in designing bioaided equipments or protective sports equipments for femur. The simulations were performed using the open source software – Elmer. The vibration patterns for first twenty modes were studied. The vibration analysis show that the natural frequency of vibration varies from 964 Hz to 10.8 kHz. The external excitation on the femur bone must be avoided to coincide with these natural frequencies; otherwise it could lead to fracture of the bone. © School of Engineering,Taylor’s University.
