Finite element analysis of hip joint prosthesis

The work deals with the proper design of hip join 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 (Co-Cr), Low-carbon stainless steel of type 316(316L SS), titanium alloy (Ti6Al4V), magnesium alloy (AZ91), carbon fiber reinforced PEEK (CF-PEEK) and carbon fiber reinforced PA -12 (CF-PA 12) have been used for implant material which are biocompatible. ANSYS finite element package has been used for modeling and analysis of the implant. The implant has been analyzed under static as well as dynamic loading. Based on those analysis, some important results have been obtained and presented in the results and discussion sections
