Modelling and Static Analysis of Femur Bone by Using CAE

Femur is leg bone of the human body undergoing more deformation. Bio mechanics is the theory of how tissues, cells, muscles, bones, organs and the motion of them and how their form and function are regulated by basic mechanical properties. The aim of this study is to create a model of real proximal human femur bone and the behaviour of femur bone is analyzed in ANSYS under physiological load conditions. A finite element model of bones is generated by using CT scan data are being widely used to make realistic investigations on the mechanical behaviour of bone structures. Orthopedic implantation is done in case of failure. Before implantation it is necessary to analyze the perfectness in case of its material property, size and shape, surface treatment, load resistance and chances of failure. Analysis is done for the stresses formed in different femur implant materials under static loading condition using ANSYS software. Analysis is done on different materials like structural steel, Aluminium Oxide and Ti-6Al-4V implant materials. Since each femur carries 1/2 the body weight, analysis is done for 245 N load, including the cases of patient carrying certain weight. And based on the analysis it can be concluded that, while comparing these two implant materials Ti-6Al-4V gave less deformation on static load conditions. TI-6AL4V is a low density material, which has excellent bio compatible and mechanical properties, it is ideal for the use of an implant in surgeries. Finally the success of implantation depends on implant material and size, implantation method and its handling by the patient.
