The hip joint is a joint that connects the thighbone to the pelvis. Over time, these joints can deteriorate and cause problems that can compromise their function. Total hip arthroplasty (THA) is needed so that sufferers of related diseases are able to return to normal activities. This process is carried out by replacing the damaged hip joint with an artificial hip joint (hip implant) consisting of a stem, femoral head, acetabular cup and backing cup. The main focus in this study is to analyze the effect of acetabular cup thickness in different material combination on hip implant design using the finite element analysis (FEA) approach method. Using standard boundary conditions referring to ASTM F2996-13, a 3-dimensional analysis using the finite element method was carried out to determine the influence of acetabular cup thickness on hip implants. MoP and MoM compositions with Co-Cr and UHMWPE materials were used in this analysis. The parameters used are taperBody von-Mises stress, total deformation and von-Mises stress on all implants. This research show that increasing the thickness of the acetabular cup has the same effect as increasing the fermoral head diameter of the implant and that implants with the highest acetabular cup thickness have better performance. However, increasing the thickness of the acetabular cup did not have a significant impact on the overall stress distribution contour of the implant.
