Designing and analysis of the femoral neck for an artificial hip joint prosthesis (original) (raw)

This study analyses femoral neck in an artificial hip joint and explores design variations using finite element analysis to compile an optimum design. An effective prosthesis should have minimal stress concentration and deformation as well as versatility to handle different loads applied at various angles. The different femoral neck designs have been modelled using Ti-6Al-4V alloy material with the following loads; 1962 N, 2354.4 N, 2746.8 N and 3139.2 N, and applied at angles; 35°, 45°, 55° and 65°. The minimum stress concentrations, deformation, stress distribution have been analyzed and compared while varying the boundary conditions. The final design was selected based on the analysis which was the most effective and versatile design consisting of a straight edged profile and trapezoidal cross section.
