Numerical Stress Analysis of Artificial Femur Bone

Abstract

Femur bone is one of the strongest bones of the human body, and it bears a maximum weight of the body with the different types of daily life activities. In the present study, we are trying to use semi-crystalline polymer such as polyetheretherketone (PEEK) and its composites such as hydroxyapatite-polyetheretherketone (HA–PEEK) as a substitute for bone implant. First a solid cylinder was designed of human bone, PEEK, and HA–PEEK, and the effect of compressive loading was analyzed using directional deformation and Von-mises stress, respectively, in the ANSYS. In the second analysis, a human femur bone was designed using software and analysis was made using ANSYS for the compressive loading. From the analysis, it can be seen that both PEEK and HA–PEEK have shown nearer Von-mises stress and directional deformation as compared to that of a natural bone. HA–PEEK had more close value as compared to the pure PEEK.
