| Popis: |
Femur bone is one of the longest bones. It is also one of the strongest bones in the human skeletal system. It absorbs and transmits the forces to the lower extremity caused due to various physical activities. The understanding of vibrational characteristics of femur helps in diagnosing various deformities and/or diseases. In the present research, two different femurs with a porosity level of 75% were considered. The modal analysis is performed with four different hyperelastic materials, namely neo-Hookean, Blatz-Ko, Ogden (first order), and Yeoh (first order). The results indicate that the Ogden first-order model is superior in predicting the natural frequencies and mode shapes in comparison to the other material models considered. It is also observed that these results are very much sensitive to the geometry as well as the material model considered. These results would be helpful in predicting the dynamic behavior of femur with different porosity levels and help in diagnosing the existence and or possibility of fracture. |
