Bio-mechanics is most difficult to carry out on thebone due to the modeling difficulty and complex forces acting onthe bones. In this study, we consider human femur bone formodeling analysis. The modal analysis is also important as thatof static analysis. We can predict the place at which the fractureoccurs. The modal analysis for three different materials is carriedout to find the feasible material for bone implants. Thesematerials are Natural bone, AZ31, and Stainless steel 316L. Thedaily activity such as walking is used as a boundary condition inour study. The femur head is fixed and 750N load is applied atthe Knee joint. The results are obtained for these materials. Themodal frequencies for Natural Femur bone vary from 0.328Hz to2.258Hz for Mode1 to Mode 10. The modal frequencies for AZ31vary from 1.502Hz to 10.292 Hz for Mode1 to Mode 10. Themodal frequencies for 316L vary from 3.120Hz to 21.150 Hz forMode1 to Mode 10. These frequencies are minimal as comparedto the natural frequency of the Femur bone. AZ31 is best suitedfor the fabrication of bone implants because of its lightweight incomparison with 316L material. Also, this is biodegradable in thehuman body over the period.
