The functioning of the normal and defective artificial hip joint during various movements has been studied with the help
of finite element analysis. The movements selected for this analysis were flexion, extension, abduction and adduction. These are
the basic movements for a hip joint combination of which results to various day to day activities. These movements have been
analyzed for both defective and non defective artificial hip joints. Three different materials namely titanium alloy, cobalt
chromium alloy and stainless steel are used for the study. A 3D modeling software, meshing software and finite element analysis
software have been used in this study. The obtained results from the analysis have been evaluated and the stresses and deflections
were compared with the acceptable values of the respective materials. The stresses exceeding the yield strength have been
concluded to result in fracture. The conclusions made helped in determining the possibility of failure of the artificial hip joint and
hence av
