  3. Abstract:
  4. In this article by employing the principle of continuum damage mechanics and solving the governing equations using finite element technique, the damage process in a composite media like a human long bone has been studied. To do this, primarily a CT scan of a femur is converted to proper model usable for a F.E. model. After applying load incrementally with monotonic nature, the state of stress or strain in each element and consequently in medium are calculated using finite element software. Based on the principle of continuum damage and the value of stress in each element, the damage rate is calculated and the mechanical properties at that point are updated for the next step of loading. This process goes on until the inception of the failure at a critical point. It is noted that the femur neck region is the most critical zone for growth of the damage in a standing position. The damage initially starts from lower part of femur and in continuation, the upper part of femur experiences more sever damage effect. © 2006 Civil-Comp Press
