F. Selection for material properties sing ium evaluated by analyzing the loss of bone density following a strain magnitude based bone remodeling the-of the elastic modulus between the implant material and the bone. For example, the elastic modulus of cobalt–chrome alloy is 210 GPa while the elastic modulus of cortical bone is only about 17 GPa [3,4]. Since the implant is much stiffer than the bone, some of the forces applied on the bone have been shielded by the prosthe-sis, which results in bone density loss. A solution to this problem is to develop new implant materials with the stiffness closing to that 2. Finite element model 2.1. Geometry of the femur The three-dimensional geometry of a femur can be established from computed tomography (CT) images. The femur geometry var-ies from person to person and it changes with age even for the same person. From the research standpoint, to simplify the exper-imental cross-validation of numerical studies, researchers fro
