Abstract :

The present article deals with the proper design of hip joint prosthesis using finite element method. Hip joint is one of the most important weight bearing and shock absorbing structure of the human body. The longevity and functionality of the implant greatly depends on the design of the implant. The shape of the implant is one of most easily recognizable feature in the design of the implant. In the present study, Cobalt-chromium (CoCr), Low-carbon stainless steel of type 316(316L SS) and a titanium alloy (Ti-6Al-4V) have been used for implant material which are biocompatible. ANSYS finite element package has been used for the modeling and analysis of the implant. The implant has been analysed under static as well as dynamic loading. Based on these analysis, some important results have been obtained.
